Consider the following reactions [SEE DIAGRAM] Then regarding given reactions which of the following — Chemical Bonding Chemistry Question

💡 Solution & Explanation

CHF3 \rightleftharpoons CF3^- + H^+ (Stabilized by inductive effect of F-atoms). CHCl3 \rightleftharpoons CCl3^- + H^+ (2p\pi-3p\pi back bonding). Due to combined effect of inductive effect of Cl-atoms and 2p\pi-3d\pi back bonding, lone pair at C-atom (negative charge) in CCl3^- is more delocalized than in CF3^-. Hence CCl3^- is more stable than CF3^- and CCl3^- is weaker lewis base than CF3^-.
