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:

  1. (a) and (b) are true
  2. (a) and (c) are true
  3. only (a) is true
  4. (b) and (c) are true

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 molecularH-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).
