Question:

Consider the given reaction. What is the correct explanation for the reaction?

the product is formed due to nucleophilic substitution

the product is formed according to Saytzeff's rule

conjugated double bond product is formed due to higher stability because of resonance stabilisation

(CH3)3CO⁻is better leaving group

Solution:

(CH3)3CO⁻is a better base than nucleophile. Hence elimination occurs. The product formed is resonance stabilised. Hence the correct explanation is given by option C.
