Question

$CH\equiv CH\stackrel{X}{\to }C{H}_2=CHCl\stackrel{Y}{\to }-(-C{H}_2-CHCl-\stackrel{\stackrel{\text{Cl}}{|}}{C}H-{)}_n-$
Fill up the blanks with suitable reagents to show synthesis of polyvinyl chloride.

• A. $X=$ $HCl,Hg{Cl}_2$; $Y=$ Polymerisation, peroxide
• B. $X=$ ${Cl}_2,{FeCl}_3$; $Y=$ Polymerisation, heat
• C. $X=$ $HCl,CuCl$; $Y=$ $H_{2}O,H^{+}$
• D. $X=$ $HCl,Hg{Cl}_2$; $Y=$ $Pt$, high pressure

Answer 1

The correct option is A $X=$ $HCl,Hg{Cl}_2$; $Y=$ Polymerisation, peroxide

$X$ is the addition of $H^{+}$ and $Cl$

$Y$ is the polymerisation reaction in the presence of peroxide,

a variety of alkenes or dienes and their derivatives are polymerised in the presence of a free radical generating initiator (catalyst) like benzoyl peroxide, acetyl peroxide, tertbutyl-peroxide etc.

Correct option is $\left[A\right]$.
