Given below are two statements:
Statement $I$: Aniline is less basic than acetamide.
Statement $II$: In aniline,the lone pair of electrons on nitrogen atom is delocalised over benzene ring due to resonance and hence less available to a proton.
Choose the most appropriate option:

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

Consider the following compounds:
$I. CH_3-CH_2-NH_2$
