The type of isomerism shown by the following compounds is

Which of the following carbonyl compounds will exhibit enolization?

(i) 

(ii)

(iii) 

(iv) 

(v) 

Given,



Which of the given compounds can exhibit tautomerism?

Assertion A : Enol form of acetone $\left[{\mathrm{CH}}_3{\mathrm{COCH}}_3\right]$ exists in $<0.1\%$ quantity. However, the enol form of acetyl acetone $\left[{\mathrm{CH}}_3{\mathrm{COCH}}_2{\mathrm{OCCH}}_3\right]$ exists in approximately $15\%$quantity.

Reason R : enol form of acetyl acetone is stabilized by intramolecular hydrogen bonding, which is not possible in enol form of acetone.
