Given below are two statements:
Statement I: 2,6-diethylcyclohexanone and 6-methyl-2-n-propylcyclohexanone are metamers.
Statement II: 2,2,6,6 - tetramethylcyclohexanone exhibits keto-enol tautomerism.
In the light of the above statements, choose the correct answer from the options given below
Official answer: C
Statement I. Both are cyclohexanones. They differ in the alkyl groups on the two sides of the carbonyl: ethyl/ethyl against methyl/propyl. The key treats them as metamers. True.
Statement II. 2,2,6,6-Tetramethylcyclohexanone has no α-hydrogen, so it cannot enolise. False.
(C)
