Amines behave as

How will you carry out the following conversions?
$(i)$ Aniline to $1,3$-dibromo-$5$-nitrobenzene
(ii) Aniline to $1,3$-dibromo-$2$-iodo-$5$-nitrobenzene

In the following compounds,the order of basicity is as follows:

The reaction of Benzenediazonium chloride with aniline yields a yellow dye. The name of the yellow dye is

Nitration of aniline also gives $m$-nitroaniline in a strong acidic medium because:

The increasing basicity order of the following compounds is:
$(1)$ $CH_3CH_2NH_2$
$(2)$ $(CH_3CH_2)_2NH$
$(3)$ $(CH_3)_3N$
$(4)$ $PhNHCH_3$
