Assertion A: Enol form of acetone
Question:

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 $\mathrm{R}$ : enol form of acetyl acetone is stabilized by intramolecular hydrogen bonding, which is not possible in enol form of acetone.

Choose the correct statement:

  1. $A$ is false but $R$ is true

  2. Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

  3. Both $A$ and $R$ are true but $R$ is not the correct explanation of $\mathrm{A}$

  4. $\mathrm{A}$ is true but $\mathrm{R}$ is false


Correct Option: , 2

Solution:

enol from of acetone is very less $(<0.1 \%)$
