When chloroform is treated with a primary amine and $KOH$,what is the characteristic smell of the product formed?

Which of the following is the strongest Bronsted base?

The structure of the compound formed when nitrobenzene is reduced by lithium aluminium hydride $(LiAlH_4)$ is

Explain the basicity of alkyl amine compounds in comparison to ammonia.

Identify the products $y$ and $x$ in the following reaction sequence:
$C_6H_5CONH_2 \xrightarrow{NaOBr} y$
$C_6H_5CONH_2 \xrightarrow[(ii) H_3O^+]{(i) C_6H_5SO_2Cl / py, \Delta} x$

Consider the following statements:
Statement-$I$: $CH_3NH_2$ is more basic than $NH_3$,but $C_6H_5NH_2$ is less basic than $NH_3$.
Statement-$II$: The order of basic strength of ethyl-substituted amines in the aqueous phase follows the order $(C_2H_5)_2NH > (C_2H_5)_3N > C_2H_5NH_2$.
