How many number of SP² hybridized carbon atoms are there in the product ‘Z’

The number of sp² hybridized carbon atoms in the product ‘Z’ is:

2

Detailed Explanation:

1. For the given reaction, the product ‘Z’ is formed after hydrolysis and subsequent heating.
2. Hydrolysis of the compound leads to the cleavage of ester and methoxy groups to form carboxylic acids and hydroxyl groups.
3. Upon heating, decarboxylation occurs, removing the carboxylic group as CO₂.
4. The final product ‘Z’ is a cyclic compound with two carbon atoms involved in double bonds (C=C). These double-bonded carbon atoms are sp² hybridized.

Concept:

• Carbon atoms involved in double bonds (C=C) are sp² hybridized.
• Hydrolysis breaks ester bonds, and heating removes carboxylic acid groups via decarboxylation.
• The product retains the structure with sp² hybridized carbons in the double bonds.
