The melting points of n-pentane (I), isopentane (II) and neopentane (III) increase in the order:

A

`II lt I lt III`

B

`III lt II lt I`

C

`III lt I lt II`

D

`I lt II lt III`

Text Solution

Verified by Experts

The correct Answer is:
A
Neopentane (III) being most symmetrical has the highest m.p. followed by n pentane while isopentane(II) being least symmetrical has the lowest m.p.
