Given below are two statements :

Statement I : Benzene is nitrated to give nitrobenzene, which on further treatment $$ \text { with } \mathrm{CH}_3 \mathrm{COCl} / \mathrm{AlCl}_3 \text { will give } $$

Statement II : $-\mathrm{NO}_2$ group is a $m$-directing, and deactivating group.

In the light of the above statements, choose the most appropriate answer from the options given below

In the reaction,

$$ 2 \mathrm{Al}(\mathrm{~s})+6 \mathrm{HCl}(\mathrm{aq}) \rightarrow 2 \mathrm{Al}^{3+}(\mathrm{aq})+6 \mathrm{Cl}^{-}(\mathrm{aq})+3 \mathrm{H}_2(\mathrm{~g}) $$

As compared with chlorocyclohexane, which of the following statements correctly apply to chlorobenzene?

A. The magnitude of negative charge is more on chlorine atom.

B. The $\mathrm{C}-\mathrm{Cl}$ bond has partial double bond character.

C. $\mathrm{C}-\mathrm{Cl}$ bond is less polar.

D. $\mathrm{C}-\mathrm{Cl}$ bond is longer due to repulsion between delocalised electrons of the aromatic ring and lone pairs of electrons of chlorine.

E. The $\mathrm{C}-\mathrm{Cl}$ bond is formed using $\mathrm{sp}^2$ hybridised orbital of carbon.

Choose the correct answer from the options given below :

Given below are two statements :

Statement I : The halogen that makes longest bond with hydrogen in HX, has the smallest covalent radius in its group.

Statement II : A group 15 element's hydride $\mathrm{EH}_3$ has the lowest boiling point among corresponding hydrides of other group 15 elements. The maximum covalency of that element E is 4 .
