Which of the following statement is/are correct ?A. Dipole moment of : B. Dipole moment of : `CH_3F gt CH_3 C1 gt CH_3 Br gt CH_3 I`C. Dipole moment of : `NH_3 gt NF_3`D. Dipole moment of : `CH_3 C1 gt CH_2 C1_2 gt CHC1_3 gt C C1_4` |

Answer» Correct Answer - A::C::D (a,c,d) (a) `I gt II gt III`. In `(I)`, intramolecular `H-bonding` decreases the bond angle `(lt 60^@)`, hence `mu` is increased. In `(III)` dipole-dipole repulsive of two `C1` atoms in `o` position increases the bond angle `(gt60^@)` and hence `mu` is decreased. (b) `CH_3 C1 gt CH_3 F gt CH_3 Br gt CH_3 I` ( c) N/A (d) N/A. |
