324353 Hoffmann's bromamide reaction is to convert

1 acid to alcohol
2 alcohol to acid
3 amide to amine
4 amine to amide
KCET - 2007
CHXII13:AMINES

324354 Assertion :
In order to convert \(\mathrm{R}-\mathrm{Cl}\) to pure \(\mathrm{R}-\mathrm{NH}_{2}\). Gabriel pthalimide synthesis can be used.
Reason :
With proper choice of alkyl halides, pthalimide synthesis can be used to prepare \(1^{\circ}, 2^{\circ}\) and \(3^{\circ}\) amines.

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.
