Question

Use a simple donor-acceptor picture: a donor lone pair becomes less available when it is strongly delocalised into an adjacent acceptor; in Bent's rule, more p character is directed toward the more electronegative substituent. Which inference is FALSE?

TestHub · Accepted Answer

Reducing donation into an electron-deficient centre generally leaves it more able to accept an external lone pair, not automatically less acidic. A, B and D are the ordinary consequences of lone-pair delocalisation, Bent's rule and added bonding interaction. Acid strengths also depend on the reference base and medium, so the word "always" cannot repair C.
