Identify an aromatic,mixed,$3^{\circ}$ amine from the following.

Primary nitro compounds react with $HNO_2$ to form crystalline solids which,on treatment with $NaOH$,give:

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

The compound which on reaction with aqueous nitrous acid $(HNO_2)$ at low temperature produces an oily nitrosoamine is

Which of the following statements is not correct?

$A$ student performed an analysis of an aliphatic organic compound '$X$' which,upon analysis,gave $C=61.01\%$,$H=15.25\%$,$N=23.74\%$. This compound,on treatment with $HNO_2/H_2O$,produced another compound '$Y$' which did not contain any nitrogen atom. However,the compound '$Y$' upon controlled oxidation produced another compound '$Z$' that responded to the iodoform test. The structure of '$X$' is:
