Consider the following molecule.
(a) H3C-H, H3C-Br
(b) H3C-NH2, H3C-OH
(c) H3C-OH, H3C-SH
The bond which is more polar in the given pairs of molecules is:
1. | C-H bond is more polar than C-Br bond; C-O is more polar than C-N and C-S bond |
2. | C-Br bond is more polar than C-H bond; C-O is more polar than C-N and C-S bond |
3. | C-Br bond is more polar than C-H bond; C-N is more polar than C-O and C-O bond is more polar than C-S |
4. | None of the above |
