a) HC=CCl
b) ClHC=CHCl
c) Cl2C=CH2
d) H2C=CHCl

Answer 1

Answer:

Explanation:

D

Answer 2

If a certain polymer has the formula $\[{\left( {-C{H_2}CC{l_2}C{H_2}CC{l_2}-} \right)_n}\]$, it is made from the monomer - $\[ClHC = CHCl\]$. Thus, the correct option is (b).

Explanation:

• Polymerisation is the process of the formation of polymers by the combination of the monomer molecules together to form a long chain of the polymer.
• Monomer is the repeating unit of the polymer.
• The process involves a chain reaction.
• If the formula of a certain polymer is $\[{\left( {-C{H_2}CC{l_2}C{H_2}CC{l_2}-} \right)_n}\]$, then the monomer must be $\[ClHC = CHCl\]$.
• The reaction can be given as: $\[n\,(ClHC = CHCl)\xrightarrow{{Polymerisation}}{\left( {-C{H_2}CC{l_2}C{H_2}CC{l_2}-} \right)_n}\]$
