The rate of reaction is maximum if $G$ is:

As compared with chlorocyclohexane, which of the following statements correctly apply to chlorobenzene?
$A$. The magnitude of negative charge is more on chlorine atoms.
$B$. The $C-Cl$ bond has partial double bond character.
$C$. $C-Cl$ bond is less polar.
$D$. $C-Cl$ bond is longer due to repulsion between delocalised electrons of the aromatic ring and lone pairs of electrons of chlorine.
$E$. The $C-Cl$ bond is formed using $sp^2$ hybridised orbital of carbon.
Choose the correct answer from the options given below:

The chemicals used for preparing acetophenone via Friedel-Crafts acylation are:
$(A)$ $C_6H_6$
$(B)$ $CH_3COCH_3$
$(C)$ $CH_3COCl$
$(D)$ Anhydrous $AlCl_3$

Two benzyne intermediates are likely to be formed equally. Reaction with amide ion can occur in two different directions with each benzyne,giving three possible products. They are formed in a $1 : 2 : 1$ ratio. Asterisk $(*)$ refers to $^{14}C$. Product $(A)$ is:

Which one of the following is not present in the nitration mixture?
