Assertion : Rate of hydrolysis of methyl chloride to methanol is higher in DMF than in water. Reason : Hydrolysis of methyl chloride follows second order kinetics.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Primary alkyl halides (here \(\mathrm{CH}_{3} \mathrm{Cl}\) ) undergo \(\mathrm{S}_{\mathrm{N}} 2\) reaction. It is a second order reaction. \(\text { Rate } \alpha[\mathrm{RX}]\left[\mathrm{Nu}^{-}\right]\) Hence, hydrolysis of \(\mathrm{CH}_{3} \mathrm{Cl}\) is favoured by non - polar medium or polar non - protic solvent (in which proton is not generated) like DMF. \(\mathrm{S}_{\mathrm{N}} 1\) reactions are favoured by polar solvents like water.

The product of which of the following reactions has the highest ease to undergo electrophilic substitution?
Product of reaction given in option (3) is toluene \(-\mathrm{CH}_{3}\) group present in toluene, activates the benzene nucleus towards electrophilic substitution due to its ' + I' effect and hyper conjugation.

Given In the above compounds correct order of reactivity in electrophilic substitution reactions (E. S. R). will be:
Allyl chloride forms very stable allyl carbocation. \(\mathrm{CH}_{2}=\mathrm{CH}-\stackrel{+}{\mathrm{C}} \mathrm{H}_{2}\) and rest two also have partial double bond character in their \(\mathrm{C}-\mathrm{X}\) bond. Thus, all the given compounds do not undergo \(\mathrm{S}_{\mathrm{N}} 2\) reaction.
