Label each bond in the following compounds as ionic or covalent (10) (a) F2 (b) LiBr (c) NaNH2 (d) CH3CH3

Covalent bond -

This type of bonding takes place between the atoms of same or similar electronegativity, is referred to as covalent bonding.

Ionic bonding -

This type of bonding takes place between the atoms of different electronegativity, is referred to as Ionic bonding.

From the question,

(a) F₂ - Covalent bonding (same atom, hence, same the electronegativity)

(b) LiBr - Ionic bonding (the electronegativity difference between Li and Br is high)

(c) NaNH₂ - Ionic bonding (the electronegativity difference between sodium and Nitrogen is high)

(d) CH₃CH₃ - Covalent bonding (since, the electronegativity difference between carbon and hydrogen is similar)
