The hydrolysis of alkyl isocyanides $(R-CH_2-NC)$ gives:

Acetanilide on nitration followed by alkaline hydrolysis mainly gives-

Assertion: Only a small amount of $HCl$ is required in the reduction of nitro compounds with iron scrap.
Reason: $FeCl_2$ formed gets hydrolysed to release $HCl$ during the reaction.

Primary nitro alkanes are obtained in good yield by oxidising aldoximes with the help of $-$

Write the reactions for the final alkylation product of aniline with an excess of methyl iodide in the presence of sodium carbonate solution.

$n$-Butylamine $(I)$,diethylamine $(II)$,and $N,N$-dimethylethylamine $(III)$ have the same molecular mass. Arrange them in the increasing order of their boiling points.
