(a) In CH3-Cl, Chlorine atom will acquire the partial negative charge since electronegativity of the Cl atom (3.0) is higher than the carbon (2.5) atom thereby leading to the attraction of the shared pair of electron towards chlorine atom giving it partial negative charge.
(b) In H-Cl, Chlorine atom will acquire the partial negative charge.
Reason: Same as above.
HCl is more polar than CH3Cl since the electronegativity difference between atoms H and Cl in HCl is more than in CH3 and Cl in CH3Cl.
