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?
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)
i) 
(ii) Addition in presence of peroxide yields product according to the anti-Markovnikov rule of addition. Anti Markovnikov rule says - in an addition reaction of a generic electrophile HX to an alkene or alkyne, the hydrogen atom of HX becomes bonded to the carbon atom that had the least number of hydrogen atoms in the starting alkene or alkyne.
