➧The angular molecule among the following is?

➫ C2H2

❱ Angular molecule is also called bent or V-shaped.

❱ It have a non-linear shape.

❱ A water molecule has two pairs of bonded electrons and two unshared lone pairs.

❱ Water (H2O) is an example of a bent molecule, as well as its analogues.

❱ The bond angle between the two hydrogen atoms is approximately 45°.

Answer 2

Answer:

Ammonia has angular structure among the given molecules.

Explanation:

• Ethylene C₂H₄ is a planner molecule with sp² hybridized carbons.
• Water H₂O accommodates bent structure because of lone pair -lone pair repulsions.
• HCN has linear structure because of the carbon in the center is sp hybridized.
• Ammonia NH₃ is a angular molecule with three N-H bonds and one lone pair.  In this case hybridization of nitrogen is sp³.
