The correct order of basicity in amines is:
$(i)$ $C_6H_5NH_2$
$(ii)$ $CH_3NH_2$
$(iii)$ $(CH_3)_2NH$
$(iv)$ $(CH_3)_3N$

Arrange the following in increasing order of their boiling points:
$I.$ $N$-Ethylethanamine
$II.$ Butanamine
$III.$ $N,N$-Dimethylethanamine

The product$(s)$ of the following reaction sequence is(are):
Aniline $\xrightarrow[\text{ii) } KBrO_3/HBr]{\text{i) Acetic anhydride/pyridine}}$ $\xrightarrow[\text{iv) } NaNO_2/HCl, 273-278 \ K]{\text{iii) } H_3O^+, \text{heat}}$ $\xrightarrow{\text{v) } Cu/HBr} \text{Product}$

Aniline under acidic medium,when chlorinated,produces :

The correct order of increasing basic nature for the bases $NH_{3}$,$CH_{3}NH_{2}$ and $(CH_{3})_{2}NH$ in aqueous solutions is:

Which of the following is more basic than aniline?
