List of top Chemistry Questions on Haloalkanes and Haloarenes asked in UP Board XII

Write the mechanism of bimolecular nucleophilic substitution reaction ($S_N2$) of alkyl halide.
The increasing order of reactivity of the following compounds in $S_N1$ reaction is:
Compounds:
A. $(CH_3)_3CBr$
B. $CH_3CH_2CH_2CH_2Br$
C. $(CH_3)_2CHCH_2Br$
D. $CH_3CH(Br)CH_2CH_3$

Explain with reasons: 
(i) Sulphuric acid is not used in the reaction of alcohol and KI. 
(ii) Haloalkanes form alkyl cyanide as chief product on reaction with KCN, while isocyanide as chief product on reaction with AgCN. 
(iii) Although chlorine is an electron withdrawing group, even then it is ortho- and para-directing in aromatic electrophilic substitution reactions.
