Detailed explanation-1: -In an ionic compound, electrons are transferred from one atom to another atom, whereas in a polar covalent compound electron pair/pairs between participating atoms are not equally shared. Q. Assertion :Chemical bonds in organic compounds are covalent in nature.

Detailed explanation-2: -In ionic bonding, atoms transfer electrons to each other. Ionic bonds require at least one electron donor and one electron acceptor. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.

Detailed explanation-3: -In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond and is sometimes called an unshared pair or non-bonding pair.

Detailed explanation-4: -Covalent bonds where electrons are not shared equally between two atoms are called polar covalent bond. As shown above, the electrons in a covalent bond between two different atoms (H and Cl in this case) are not equally shared by the atoms.

Detailed explanation-5: -Ionic Bonds Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
