In an organic reaction,explain the reactant,substrate,and products obtained. What is the mechanism of the reaction?

In the reaction given below,the total number of atoms having $sp^2$ hybridization in the major product $P$ is. . . . .

Match the reactions in Column-$(I)$ with the type of reaction mechanism in Column-$(II)$.

Column-$(I)$ (Reaction)	Column-$(II)$ (Type of Reaction)
$(A)$ $\text{Cyclohexene} + Br_2 \xrightarrow{\Delta, uv} \text{3-Bromocyclohexene}$	$(i)$ $\text{Nucleophilic substitution}$
$(B)$ $\text{4-Hydroxybenzyl alcohol} + HCl \xrightarrow{\Delta} \text{4-Hydroxybenzyl chloride}$	$(ii)$ $\text{Electrophilic addition}$
$(C)$ $\text{Cyclohexene} + Br_2 \xrightarrow{CCl_4} \text{1,2-Dibromocyclohexane}$	$(iii)$ $\text{Free radical substitution}$
$(D)$ $\text{Toluene} + Cl_2 \xrightarrow{Fe, \text{dark}} \text{o/p-Chlorotoluene}$	$(iv)$ $\text{Electrophilic aromatic substitution}$

Ionic reactions with organic compounds proceed through:
$(A)$ Homolytic bond cleavage
$(B)$ Heterolytic bond cleavage
$(C)$ Free radical formation
$(D)$ Primary free radical
$(E)$ Secondary free radical
