What happens when CH3-Br is treated with KCN?
It is a nucleophilic substitution reaction. The nucleophile CN- substitutes Br- because cyanide is strong nucleophile than bromide. The reaction is as follows:
CH3-Br+KCN --> CH3-CN+HBr
Answer the following:
(i) Haloalkanes easily dissolve in organic solvents, why?
(ii) What is known as a racemic mixture? Give an example.
(iii) Of the two Bromo derivatives, C6H5CH(CH3)Br and C6H5CH(C6H5)Br, which one is more reactive in Sn1 substitution reaction and why?
Chlorobenzene is extremely less reactive towards a nucleophilic substitution reaction. Give two reasons for the same?
Although chlorine is an electron withdrawing group, yet it is ortho-, Para-directing in electrophilic aromatic substitution reactions. Explain why it is so?
