| Read the assertion and reason carefully to mark the correct option out of the options given below: |
| Assertion: Freezing point of neopentane is more than n-pentane. |
| Reason: Increase in Van der Waals forces increases freezing point. |
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
[b] Neopentane is more symmetric than n-pentane and it is expected to show more stable crystal lattice than that of n-pentane and thus have high melting point.
