The total number of valence electrons in the tetramethyl amonium ion , (CH3) 4N+, is?

Question

a) 8 b) 32 c) 24 d) 33 e) 18

Answer 1

3 x pairs on each of the four methyl groups, and 4 x pairs on the central N atom. Be careful about the electrons which are shared - ie all the N pairs.

So I would say 32.
