Question

which of these substances cannot behave as a lewis base in an aq solution

a- Co

b- O2-

c- ag+

d- Nh3

e-Cn-

Answer 1

Answer #1

lewis base => electron pair donar species are called as lewis base

a) CO = Carbon monoxide here the oxygen has two lone pairs and then it can donate electron pair and acts as lewis base

b) O^2- => here the oxygen has three lone pairs and then it can donate electron pair and acts as lewis base

c) Ag+ => the ion is cation and then it accepts the electron pair rather than donating and then acts as lewis acid not base

d) NH3 => here the nitrogen has one lone pair and then it can donate electron pair and acts as lewis base

e) CN^- => here the nitrogen has one lone pair and then it can donate electron pair and acts as lewis base

answer => C
