What product will be formed from the Hofmann exhaustive methylation of the following compound?
$CH_3-CH(CH_3)-CH_2-NH-CH_2-CH_2-CH_3 \xrightarrow[(i) CH_3I (excess), (ii) Ag_2O, (iii) \Delta]{} \text{Product}$

$R-CONH_2 + xNaOH + Br_2 \to R-NH_2 + 2NaBr + Na_2CO_3 + H_2O$
The number of moles of $NaOH$ used in the above Hoffmann bromamide reaction is:

What is the product formed when benzene diazonium chloride reacts with ethanol?

Which substance is responsible for the characteristic smell of mustard oil?

Account for the following:
$(i)$ $pK_{b}$ of aniline is more than that of methylamine.
$(ii)$ Ethylamine is soluble in water whereas aniline is not.
$(iii)$ Methylamine in water reacts with ferric chloride to precipitate hydrated ferric oxide.
$(iv)$ Although amino group is $o-$ and $p-$ directing in aromatic electrophilic substitution reactions,aniline on nitration gives a substantial amount of $m$-nitroaniline.
$(v)$ Aniline does not undergo Friedel-Crafts reaction.
$(vi)$ Diazonium salts of aromatic amines are more stable than those of aliphatic amines.
$(vii)$ Gabriel phthalimide synthesis is preferred for synthesising primary amines.

Arrange the following in increasing order of their basic strength:
$(i)$ $C_2H_5NH_2, C_6H_5NH_2, NH_3, C_6H_5CH_2NH_2$ and $(C_2H_5)_2NH$
$(ii)$ $C_2H_5NH_2, (C_2H_5)_2NH, (C_2H_5)_3N, C_6H_5NH_2$
$(iii)$ $CH_3NH_2, (CH_3)_2NH, (CH_3)_3N, C_6H_5NH_2, C_6H_5CH_2NH_2$
