How the following conversion can be carried out?
Chlorobenzene to p-nitrophenol
Out of (CH3)3 C-Br and (CH3)3 C-I, which one is more reactive towards SN1 and why?
Assertion: Presence of a nitro group at ortho or para position increases the reactivity of haloarenes towards nucleophilic substitution.
Reason: Nitro group, being an electron-withdrawing group decreases the electron density over the benzene ring.
Which of the following compounds will give racemic mixture on nucleophilic substitution by
(a)
(b)
(c)

Allyl chloride is hydrolysed more readily than n-propyl chloride. Why?
The number of carbon atoms present in the product B is:
Assertion: Chlorobenzene is resistant to nucleophilic substitution reaction at room temperature.
Reason (R): C–Cl bond gets weaker due, to resonance.
Why haloarenes are not reactive towards nucleophilic substitution reaction? Give two reactions.
