1) Which one of the following molecules is the most polarizable?

Question

a) H3C – I b) H3C – CH3
c) H3C – F

d) H3C – H e) H3C – OH

I chose H3C-I as the answer because the mm was the greatest. I added the mm of H, C, and I and got 141.934. Did I do this correctly?

Answer 1

I would have chosen c since the electronegativity of F is higher than any of the others.

Answer 2

I think it's A because you are looking at increasing molar mass in the halogens
