CBSE Class 12 · 2009 · Delhi · Haloalkanes and HaloarenesShort Answer

Auto-oxidation of chloroform in air and light produces a poisonous gas known as:

Assertion (A): Inversion of configuration is observed in the S${}_{\mathrm{N}}$2 reaction.
Reason (R): The reaction proceeds with the formation of a carbocation.

Account for the following:
(a) Haloalkanes react with AgCN to form isocyanides as the main product.
(b) Allyl chloride shows high reactivity towards the S${}_{\mathrm{N}}$1 reaction.
(c) Haloarenes are extremely less reactive towards nucleophilic substitution reactions.

Write equations for the following:
a) oxidation of chloroform by air and light
b) reaction of chlorobenzene with CH${}_3$Cl / anhydrous AlCl${}_3$

The substitution reaction of an alkyl halide mainly occurs by the SN1 or SN2 mechanism. Whatever mechanism alkyl halides follow for the substitution reaction to occur, the polarity of the carbon-halogen bond is responsible for these substitution reactions. The rate of SN1 reactio …
