The decreasing order of the anti-knocking value of octane number of the following is: (I) `CH_(4)` (II) `C_(2)H_(6)` (III) `C_(3)H_(8)` (IV) `C_(4)H_(10)`

A

(a) (I) > (II) > (III) > (IV)

B

(b) (IV) > (III) > (II) > (I)

C

(c) (I) > (III) > (II) > (IV)

D

(d) (IV) > (II) > (III) > (I)

Text Solution

Verified by Experts

The correct Answer is:
A
