Reaction $(B)$:
$CH_3-CH=CH-Ph \xrightarrow[NaBH_4]{Hg(OAc)_2 / H_2O}$ products.
Correct statement is:

Which compounds give $\beta$-elimination reactions? What are their main products?

Which one among the following undergoes dehydrohalogenation most readily?

Identify the major product formed from the following reaction: $1$-methylcyclohex-$1$-ene $\xrightarrow[(ii) AgNO_2]{(i) HCl} ?$

Identify the incorrect option from the following:

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$ :
Assertion $(A)$ : $S_N2$ reaction of $C_6H_5CH_2Br$ occurs more readily than the $S_N2$ reaction of $CH_3CH_2Br$.
Reason $(R)$ : The partially bonded unhybridized $p$-orbital that develops in the trigonal bipyramidal transition state is stabilized by conjugation with the phenyl ring.
In the light of the above statements,choose the most appropriate answer from the options given below:
