Vedclass · Answer

(B) $1$. Ethyl chloride $(C_2H_5Cl)$ on reduction with $Zn-Cu$ couple and alcohol gives ethane $(C_2H_6)$. This is correct.$2$. The reaction of methyl magnesium bromide $(CH_3MgBr)$ with acetone $(CH_3COCH_3)$ gives tert-butanol ($2$-methylpropan-$2$-ol),not butanol-$2$. Thus,statement $B$ is wrong.$3$. Alkyl halides follow the reactivity sequence $R-I > R-Br > R-Cl > R-F$ due to the decreasing bond dissociation energy of the $C-X$ bond. This is correct.$4$. $C_2H_4Cl_2$ exists as two isomers: $1,1$-dichloroethane and $1,2$-dichloroethane. This is correct.

Column-$I$ (Reactants)	Column-$II$ (Products)
$A$. $H_2C=CH_2 + Br_2 \xrightarrow{CCl_4}$	$i$. $CH_3CH_2CH_2Br$
$B$. $CH_3CH=CH_2 + HI \rightarrow$	$ii$. $BrCH_2-CH_2Br$
$C$. $C_6H_5N_2^+X^- + KI \rightarrow$	$iii$. $CH_3CHICH_3$
$D$. $CH_3CH=CH_2 + HBr \xrightarrow{peroxide}$	$iv$. $C_6H_5I$
