Verified by Toppr

The decreasing order of the acidic character of the following is (I) > (III) > (II) > (IV)
Cycloalkanes are more acidic than the corresponding alkanes.
Cyclopropane is most acidic and n butane is least acidic.
In general alkanes are inert towards acids and bases due to non polar nature of C-C and C-H bonds and their inability to donate or accept electrons.
