Based on the structural applications of inductive, mesomeric, and hyperconjugative effects, which of — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Statement A is true ($-F$ has a stronger $-I$ effect than $-Cl$). Statement B is true (Phenoxide is resonance stabilized, but phenol fails the bicarbonate test because it's weaker than $H_2CO_3$). Statement C is true (50% s-character in $sp$ vs 33% in $sp^2$ makes the ethynyl proton more acidic). Statement D is strictly false; formic acid is STRONGER because the $+I$ effect of the methyl group in acetic acid destabilizes the conjugate base.
