Which one is the correct order of acidity ?

A

`CH_(3)- CH_(2) gt CH_(2)=CH_(2) gt CH_(2)-C-=CH gt CH-=CH`

B

`CH_(2)=CH_(2) gt CH_(2)-CH=CH_(2) gt CH_(2)-C-=CH_(2) gt CH_(3)-CH_(2)`

C

`CH-=CH gt CH_(3)- C-=CH gt CH_(2)=CH_(2) gt CH_(3)-CH_(3)`

D

`CH-=CH gt CH_(2)= CH_(2) gt CH_(3)-=CH gt CH_(3)-CH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`CH-=CH gt CH_(3)C-=CH gt CH_(2)=CH_(2) gt CH_(3)-CH_(3) to` Alkanes, alkenes and alkynes follow the following trend in their acidic behaviour.
(i) `HC-=CH gt H_(2)C=CH_(2) gt CH_(3)-CH_(3)`
(ii) `HC-= CH gt CH_(3)- C-=CH gt gt CH_(3)-C-=C-CH_(3)`
