Which one is the correct order of acidity ?

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
Correct order of acidic strength is:
`underset("(two acidic hydrogens)")(H-C -=CH) gt underset("(one acidic hydrogen)")(CH_(3) -C -=CH) gt CH_(2) = CH_(2) gt CH_(3) - CH_(3)`
