Question
Choose the set of reagents which will BEST achieve the desired conversion: NH_3, pyridine HONO NaBF_4 HNO_3, H_2SO_4 Sn, conc. HCl, Delta aq. NaOH HONO NaBF_4 SOCl_2 NH_3, pyridine HONO NaBF_4 F_2, FeF_3 Despite the fact that the enolate ion is the better resonance contributor (see below), it is the alpha- carbon that usually reacts with an electrophile in alpha-substitution. Why? The carbon is more hindered. A negatively-charged carbon is a stronger nucleophile than a negatively-charged oxygen The moon is in the seventh house. The carbon is more electrophilic than the oxygen.Explanation / Answer
3----B series
