Question

Which of the statements are WRONG about the nucleophilic addition reaction of alkenes and alkynes?

• A. Addition of nucleophile $( R \overset{\ominus}{O} )$ to an alkene gives an alkyl carbanion whose negative charge is on the $s p^3$-hydridised $C$ atom
• B. Addition of nucleophile $( R\overset{\ominus}{O} )$ to an alkyne gives a vinyl carbanion whose negative charge is on the $s p^2$-hybridized $C$ atom. Due to more $s$ character, it is readily formed and more stable than alkyl carbanion formed with alkenes. So alkynes are more reactive than alkenes towards NA reaction
• C. Strong electron-withdrawing inductive effect (-I) further stabilizes both vinyl and alkyl carbanion
• D. Strong electron-donation inductive effect $(+ I )$ further stabilises both vinyl and alkyl carbanion

Answer 1

Answer: (D)

Statements are self explanatory
