Give dipole arrow of the following molecules. (i) HF (ii) CO (iii)

1.	Give dipole arrow of the following molecules. (i) HF (ii) CO (iii)
Answer» Solution :(i) H `OVERSET( rarr )(-)` F : is negative and H is positive So, bonding electron pair is nearer to negative ion H : F, Thus `H^(delta +) F^(delta -)` (II) `C overset(rarr)(-) O C^(delta +) O^(delta-)` (iii) Cl - Cl is NON polar , So, electron pair is in centre , Cl : Cl and arrow is not put.
