(a)

Interpretation Introduction

Interpretation:

$\text{C}-\text{C}$ bond in ${\text{H}}_{\text{3}}{\text{CCH}}_{\text{3}}$ is whether ionic, covalent or polar covalent or ionic has to be determined.

Concept Introduction:

• Ionic bond takes place between a metal and a nonmetal where ions having opposite charges are held by electrostatic attraction. If the difference in electronegativity between the atoms in a bond is 2.0 or more than 2.0, then it is an ionic bond.
• Covalent bond is formed when electrons are shared between atoms. When the electronegativity between two atoms is similar, sharing of electron in the bond is equal and is called nonpolar molecules. If the difference in electronegativity between the atoms in a bond is less than $0.3$, then it is a nonpolar or covalent bond.
• While formation of a bond, there is a chance that electronegativity between the atoms are high. It tends to make the bond partially ionic and are called polar molecule. If the difference in electronegativity between the atoms in a bond is between $0.3$ and $2.0$, then it is a polar covalent bond.

Interpretation Introduction

Interpretation:

$\text{K}-\text{I}$ bond in $\text{KI}$ is whether ionic, covalent or polar covalent or ionic has to be determined.

Concept Introduction:

• Ionic bond takes place between a metal and a nonmetal where ions having opposite charges are held by electrostatic attraction. If the difference in electronegativity between the atoms in a bond is 2.0 or more than 2.0, then it is an ionic bond.
• Covalent bond is formed when electrons are shared between atoms to form a bond. When the electronegativity between two atoms is similar, sharing of electron in the bond is equal and is called nonpolar molecules. If the difference in electronegativity between the atoms in a bond is less than $0.3$, then it is a nonpolar or covalent bond.
