JEE Main Chemistry question

The boiling point of water is high because

(A)Water molecule is linear
(B)Water molecule is not linear
(C)Water molecules possess covalent bond between H and O
(D)Water molecules associate due to H-bondingCorrect

Answer: (D)

Solution

Water's anomalously high boiling point (100°C, compared to much lower values for similar-sized molecules like HS) arises because extensive intermolecular hydrogen bonding causes water molecules to associate into clusters, requiring extra energy to separate them into
