Question 58

Phthalimide is made to undergo following sequence of reactions:

Total number of $$\pi$$ bonds present in product 'P' is/are ______

Correct Answer: 8

Solution

Reagent: $$\text{KOH}$$ (Base)

Transformation: The base removes the acidic proton from the imide nitrogen ($$-\text{NH}-$$), creating a nucleophilic phthalimide anion ($$\text{N}^-$$)

Reagent: Benzyl chloride ($$\text{C}_6\text{H}_5\text{CH}_2\text{Cl}$$). Reaction happens via Nucleophilic Substitution ($$\text{S}_\text{N}2$$) pathway

Transformation: The nucleophilic nitrogen attacks the benzylic carbon of benzyl chloride, displacing the chloride leaving group.
