In the given reaction,

The number of

π

electrons present in the product ' P ' is ____.

Answer: 4

Solution

The reaction involves the conversion of furan (a five-membered aromatic heterocycle) to a product P. Furan has 6 π electrons (aromatic). Upon reaction with the given reagent, the product P appears to be a non-aromatic or partially unsaturated compound. Based on the structure shown in the solution, product P contains 2 C=C double bonds, contributing 4 π electrons total.
