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
- A(a) and (b) are true
- B(a) and (c) are true
- Conly (a) is true
- 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).
