Answer: Option B. -> CH3Cl,CH3F,CH3Br
:
B
Due to much smaller size of F than Cl, the dipole moment of CH3F is lower than that of CH3Cl.

B
Due to much smaller size of F than Cl, the dipole moment of CH3F is lower than that of CH3Cl.
Answer: Option D. -> I
:
D
Boiling points increases as the number of carbon atoms increases in the alkyl halides. Therefore the B.P of II, III and IV with four carbon atoms is higher than that of I with three carbon atoms. Further, the B.P decreases with the number of branches. Thus the B.P of the four alkyl halides increases in the order I< IV< III< II.

Answer: Option A. -> SN1 mechanism
:
A
The outgoing nucleophile does not leave the reactant and therefore, attack is mainly from backside .
