Consider the following molecules and statements related to them: (a) (B) is more likely to be crystaline than (A) (b) (B) has higher boiling point than (A) (c) (B) dissolves more readily than (A) in water Identify the correct option from below:

Options

  1. A(a) and (b) are true
  2. B(a) and (c) are true
  3. Conly (a) is true
  4. D(b) and (c) are true

Correct answer

D. (b) and (c) are true

Step-by-step solution

The molecules of B are joined by intermolecular hydrogen bonding and molecules of A associated through dipole-dipole interactions.Hence, the B is more likely to be crystalline than A. Due to inter molecular H - Bonding in B , than A ,   B is more soluble and having more boiling point than A . *Note: All the three statements given in the question are correct but the given answer according to NTA, is statements (b) and (c).
