Which of the following carbonyl compounds will exhibit enolization? (i) (ii) (iii) (iv) (v)
Options
- Ai ,   ii and iii
- Bii ,   iii and iv
- Ciii ,   iv and v
- Di ,   iii and v
Correct answer
B. ii ,   iii and iv
Step-by-step solution
For the enolization carbonyl compound. Carbonyl compound must contain at least one α -H Compunds (i) , (v) have not alpha hydrogen so these compounds will not show enolization. Compounds (ii),(iii),(iv) have alpha hydrogen so these compound wil show enolization. (i) (ii) (iii) (iv) (v) ( i ) c o m p o u n d   = 0   ( α - H ) ( i i ) c o m p o u n d   = 2   ( α - H ) ( i i i ) c o m p o u n d   = 5   ( α - H ) ( i v ) c o m p o u n d   = 2   ( α - H )
