Question

Which of the following species is the least nucleophilic?A) (CH3)3NB) BF3C) H2OD) (CH3)3CO-E) CN-

Answer 1

BF3

Step-by-step explanation:

BF3 possesses an open sextet. This implies that the octet around the central atom is incomplete. As a result of this, BF3 will function as an electrophile rather than as a nucleophile.

Hence of all the compounds listed in the options, BF3 is the least nucleophillic.
