Long Answer Type
Short Answer TypeGive reasons:
The presence of nitro group (–NO2) at o/p positions increases the reactivity of haloarenes towards nucleophilic substitution reactions.
Which alkyl halide from the following pair is chiral and undergoes faster SN2 reaction?
Among the given pair of compounds, alkyl halide (b) has a chiral centre.
The alkyl halide (a) does not contain a chiral centre and it also gives faster SN2 reaction as SN2 is more favourable in primary alkyl halides.
Out of SN1 and SN2, which reaction occurs with
(a) Inversion of configuration
(b) Racemisation
Draw the structure of major monohalo product in each of the following reactions:
i) 
ii)
Switch
