285528 Prolonged exposure of chloroform in humans may cause damage to liver. It is due to the formation of the following compound

285529 Which of the following halides undergoes hydrolysis on warming with water/aqueous NaOH ?

Ans:d
Exp:(d) Chlorobenzene does not react with aqueous NaOH at room temperature but presence of electron withdrawing groups like\(-\mathrm{NO}_2,-\mathrm{CN}\), at ortho or para position enhance the reactivity of aryl halides towards nucleophilic substitution.
Further, greater the number of such groups at oand \(p\)-position wr.t. the halogen, more reactive is the haloarene. Hence, 1-chloro-2, 4, 6trinitrobenzene will be hydrolysed the most on warming with water/aqueous NaOH .

285530 The compound having longest\(\mathrm{C}-\mathrm{Cl}\) bond is

285531 Which of the following statements is true in case of alkyl halides?
