As compared with chlorocyclohexane, which of the following statements correctly apply to chlorobenzene?
The magnitude of negative charge is more on chlorine atom.
The C--Cl bond has partial double bond character.
C--Cl bond is less polar.
C--Cl bond is longer due to repulsion between delocalised electrons of the aromatic ring and lone pairs of electrons of chlorine.

Choose the correct set of reagents for the following conversion trans $\left( Ph - CH = CH - CH _3\right) \rightarrow \operatorname{cis}\left( Ph - CH = CH - CH _3\right)$

Given below are two statements, one is labelled as Assertion $A$ and the other is labelled as Reason $R$
Assertion A: Carbon forms two important oxides - $CO$ and $CO _2 .CO$ is neutral whereas $CO _2$ is acidic in nature
Reason R : $CO _2$ can combine with water in a limited way to form carbonic acid, while $CO$ is sparingly soluble in water
In the light of the above statements, choose the most appropriate answer from the options given below

The molality of a 10% (v/v) solution of di-bromine solution in $\text{CCl}_4$ (carbon tetrachloride) is $x$. $x = \, \_\_\_\_\ \times 10^{-2} \, \text{M}$. (Nearest integer)
Given:
Molar mass of $\text{Br}_2 = 160 \, \text{g mol}^{-1}$
Atomic mass of $\text{C} = 12 \, \text{g mol}^{-1}$
Atomic mass of $\text{Cl} = 35.5 \, \text{g mol}^{-1}$
Density of dibromine = $3.2 \, \text{g cm}^{-3}$
Density of $\text{CCl}_4 = 1.6 \, \text{g cm}^{-3}$
