You are watching: Which of the following compounds contains both ionic and covalent bonds
3) potassium nitrate
Explanation:
An ionic bond is formed when an element totally transfers that valence electron to an additional element. The facet which donates the electron is well-known as electropositive element and forms a positively fee ion dubbed as cation. The aspect which accepts the electrons is known as electronegative element and also forms a negatively charged ion dubbed as anion.
A covalent shortcut is created when an aspect shares its valence electron with another element. This shortcut is formed in between two no metals.
1. Potassium chloride : is made up of ionic bond between metal and also non metal.
2. Potassium hydride :
3) potassium nitrate : made up of ionic bond and is consisted of of covalent bond between two non steels nitrogen and also oxygen.
4) potassium oxide:
Thus potassium nitrate has both ionic and covalent bonds.
The exactly answer is
Explanation:
Ionic compound are characterized as the compounds i beg your pardon are developed by the complete transfer of electrons from one atom to an additional atom. In this compounds, oppositely fee ions room attracted towards each various other to kind a compound.
Covalent compounds are characterized as the compounds i m sorry are developed by the sharing of electrons between the atoms creating a compound. In this compounds, no ions are formed.
Monoatomic ions are the ions which have actually only one atom having a charge on it.
Polyatomic ions are characterized as the ion which have actually two or more than two atoms and also the atoms form covalent bond.
Potassium ion will type ionic bond v both monoatomic and polyatomic ions, but in polyatomic ions, the atoms kind covalent bonds.
Compound that potassium in i beg your pardon both covalent and also ionic bonds are current is where ionic shortcut is present in between potassium and also chromate ions. Covalent bond is present in between chromium and also oxygen atoms.
Compound of potassium having only ionic bond is KCl, whereby ionic shortcut is present in between potassium and chlorine atoms.
Hence, the correct answer is
The correct answer is choice (A).
Explanation:
Covalent bonds are those binding in which share of an electrons is existing in between the 2 atoms. Normally this form of bonding is found when electro-negativity difference between is an extremely less or zero.
Ionic bonds room those bonds in which complete transfer that an electron from one atom to one more atom is present.Generally this form of bonding is uncovered when electro-negativity difference between two atoms is an extremely large.
link
Bond between carbon and also oxygen atoms in lead carbonate ion is a covalent bond. Gift a ploy-atomic ion it carries 2- charge.Calcium ion gift 2+ charge will kind ionic bond through carbonate ion.
The exactly answer is option (A).
Explanation:
Covalent bonds are those bond in which share of an electron is current in in between the 2 atoms. Typically this type of bonding is found when electro-negativity difference between is an extremely less or zero.
Ionic bonds space those binding in which complete transfer that an electron from one atom to one more atom is present.Generally this type of bonding is found when electro-negativity difference between two atom is really large.

Bond in between carbon and also oxygen atom in lead carbonate ion is a covalent bond. Being a ploy-atomic ion that carries 2- charge.Calcium ion gift 2+ fee will kind ionic bond through carbonate ion.
The exactly answer is choice d.
Explanation:
Ionic shortcut is formed when over there is finish transfer of electron from one atom to another. The atom i m sorry looses electron is well-known as electropositive atom and also the atom which gains electron is well-known as electronegative atom. Ionic compound, when dissolved in water will certainly dissociate into its respective ions.
Covalent link is identified when over there is share of electrons between the 2 atoms forming a compound. It does no dissociate into its respective ions, when dissolved in water.
From the provided options, the compound having actually both ionic and also covalent bonds is NaOH.
Here, covalent shortcut is present in between O and also H forming ion.
When NaOH is liquified in water, the equation follows:
As, it it s okay dissociated into its ions, because of this ionic shortcut is additionally present.
Hence, the exactly answer is choice d.
Ionic compound : Ionic compound are the compound in i m sorry atoms space bonded with ionic bond.
Ionic bond are formed by the finish transfer that electrons. The atom which looses the electron is considered as electropositive atom and also the atom i beg your pardon gains the electron is well-known as electronegative atom. This bonds are formed in between one metal and also one non-metal.
Covalent link : Covalent compound space the compounds in i m sorry atoms room covalently bonded.
Covalent bonds are created by the equal sharing of electrons. These bonds are commonly formed between two non-metals.
As per provided options, and also are the ionic compounds in i beg your pardon "K" and also "Ca" are the metals and "I" and "Cl" space the non-metals that space bonded through the ionic bond.
The alternative is a covalent compound in which the carbon, hydrogen and also bromine atoms space non-metal that space bonded with the covalent bond.
While the option, is the link that includes both ionic and also covalent bonds. In NaCN compound,
Hence, the correct alternative is, (D) NaCN
d. AlCl3
Explanation:
In AlCl₃ each Al³⁺ cation is surrounded by three Cl⁻ anion. Al³⁺ has actually a little ionic radius providing it a high charge density whereas Cl⁻ has a huge ionic radius, short charge, and also easily polarizable. Al³⁺ traction one electron from each of the three Cl⁻ ion thus offering the Al-Cl bond a covalent character.
D.NaCN has both ionic and covalent bonds
Further explanation
Elements based on electrical conductivity deserve to be separated into two elements, specific metal elements (conductors) and also non-metals (non-conductors / insulators)
In contemporary periodic systems, the metal facet is usually located top top the left when the non-metal is on the right.

The formation of electron configuration such as noble gases deserve to be done by share electrons through covalent bonds or hand end electrons through ionic bonds
1. Ionic bonding
Bonding the occurs because of electron handover. Can happen in metal and non-metal atoms. To get stability, atoms release or tie electrons to get stable electron regulation from noble gases
2. Covalent bonding
Bonding the occurs because of shared usage of electron pairs
The two bound atoms contribute their electrons to produce bonds
Generally occurs in non-metallic elements
The small difference in electronegativity in between two nonmetal facets results in a non-polar covalent bond. Conversely, the higher electronegativity distinction makes the compound ionic
So if the electronegativity difference in between the atom is greater than 1.7, the compounds developed are ionic.
A. KI
An ionic bond occurs in between metal K⁺ (group 1A) and non-metal I⁻ (group 7A)
B. CaCl₂
An ionic shortcut occurs between the Ca²⁺ steel (group 2A) and the non-metal Cl⁻ (group 7A)
C. CH₂Br₂
A covalent shortcut occurs in between C, H and Br (all non-metal)
D.NaCN
An ionic bond occurs in between the Na + steel (group 1A) and also CN- (cyanide) and the CN covalent bond in between nonmetal C (class 4A) and nonmetal N (VA group)
