#1

Arrange benzene, n-hexane and ethyne in decreasing order of acidic behaviour. Also give reason for this behaviour.


#2

The hybridisation state of carbon in the given compounds is

Acidic character increases with increase in s-character of the orbital. Hence, decreasing order of acidic behaviour of ethyne > benzene > hexane
