Which of the following structural parameters and bonding characteristics correctly differentiate alk — Hydrocarbons Chemistry Question

💡 Solution & Explanation

(A) Bond length decreases as bond order increases. (B) Bond energy increases with bond order. (C) The $sp$ -carbon is highly electronegative, making terminal $C-H$ protons weakly acidic. (D) is false; alkynes are generally less reactive than alkenes towards electrophiles because the $\pi$ -electrons are more tightly held by the highly electronegative $sp$ -hybridized carbons.
