$(I)$ $B + AN{O_3} \longrightarrow BN{O_3} + A$
$(II)$ $A + HCl \longrightarrow ACl + \frac{1}{2}\,{H_2}$
$(III)$ $D + ECl \longrightarrow DCl + E$
$(IV)$ $D + HN{O_3} \longrightarrow {H_2}$ gas is not evolved
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:

$C{O_{(g)}} + \frac{1}{2}{O_{2(g)}} \to C{O_{2(g)}}$
How are $\Delta E$ and $\Delta H$ releated for the reaction?
