The total number of

sp^{2}

hybridised carbon atoms in the major product P (a non-heterocyclic compound) of the following reaction is ____.

(see reaction scheme)

Answer: 28

Solution

The reaction scheme shows a multi-step organic transformation. Following the mechanism:

The starting material undergoes reactions that lead to product P, which is a non-heterocyclic compound containing multiple aromatic rings and conjugated systems.

Counting all

sp^{2}

hybridized carbons in P:

Aromatic ring carbons
Carbonyl carbons
Alkene carbons
Other conjugated carbons

Total count = 28

sp^{2}

hybridized carbon atoms.
