Question

Which plastic is obtained from $CHC{l_3}$ as follows
$2CHC{l_3}\xrightarrow[{sb{F_3}}]{{HF}}X\xrightarrow{{{{800}^ \circ }C}}Y\xrightarrow{{Polymerisation}}Plastic$
Bakelite
Teflon
Polythene
Perspex

Answer 1

Hint: Here we have received the reactant as Chloroform as firstly we have to react as in the presence of hydrogen fluoride and Antimony Tri Fluoride we get the first product after which we have to react that compound back on ${800^ \circ }C$ after which we start the process of Polymerisation and we have to say that from that whole reaction which plastic we ate going to be obtained.



Formula Used:

Complete step-by-step answer:As this reaction is getting completed in three different parts so we complete the whole reaction by one by one in every individual part,
So, by taking the first part getting the reaction of Chloroform as in the presence of hydrogen fluoride and Antimony Tri Fluoride we get,
$2CHC{l_3}\xrightarrow[{sb{F_3}}]{{HF}}2CH{F_2}Cl$
As in the above reaction we get the X product of the following reaction.
Now, by getting reaction of $2CH{F_2}Cl$ as giving it ${800^ \circ }C$ we get the reaction as,
$2CH{F_2}Cl\xrightarrow{{{{800}^ \circ }C}}C{F_2} = C{F_2}$
As we get Tetrafluoro ethylene from the above reaction.
Now getting the final reaction of Polymerization we get the product as,
$C{F_2} = C{F_2}\xrightarrow{{Polymerisation}}{( - C{F_2} - C{F_2} - )_n}$
As we get the product in the above reaction now getting the whole reaction in one form for the representation the whole reaction is,
$2CHC{l_3}\xrightarrow[{sb{F_3}}]{{HF}}2CH{F_2}Cl\xrightarrow{{{{800}^ \circ }C}}C{F_2} = C{F_2}\xrightarrow{{Polymerisation}}{( - C{F_2} - C{F_2} - )_n}$
As a result, we get the final product as Teflon.
Hence, the correct option is (B).



Option ‘ ’ is correct

Additional Information:

Note: In this question we get a term named Teflon. Teflon is mostly used in the manufacturing process of waterproof product and also used in the making of non-stick utensils. These are the some major items which are manufactured using Teflon.
