Question

Find out the appropriate reactions and match the columns. A, B and C suitably:

Reactants (A)	Products(B)	Name of the reaction(C)
${CH}_{3} - {CH}_{3} + {CI}_{2}$	${CO}_{2} + H_{2} O$	Addition reaction
$C_{2} H_{6} + O_{2}$	${CH}_{2} = {CH}_{2}$	Thermal cracking
${nCH}_{2} = {CH}_{2}$	${CH}_{2} = {CH}_{2} + {CH}_{4}$	Substitution reaction
${CH}_{3} - {CH}_{2} — {CH}_{3}$	${CH}_{3} — {CH}_{2} CI + HCI$	Polymerisation
$CH \equiv CH + H_{2}$	$[- {CH}_{2} - {CH}_{2} -]_{n}$	Combustion

Accepted Answer

The complete reaction for the reactants is ${CH}_{3} - {CH}_{3} + {CI}_{2} \to {CH}_{3} - {CH}_{2} Cl + HCl$ , It is a chlorination of ethane which is an example of substitution reaction.

The complete reaction for the reactants is $2 C_{2} H_{6} + 7 O_{2} \to 4 {CO}_{2} + 6 H_{2} O$ , It is a combustion of ethane.

The complete reaction for the reactants is ${nCH}_{2} = {CH}_{2} \to [- {CH}_{2} - {CH}_{2} -]_{n}$ , It is polymerisation of ethene and the product is polyethene.

The complete reaction for the reactants is ${CH}_{3} - {CH}_{2} — {CH}_{3} \to {CH}_{2} = {CH}_{2} + {CH}_{4}$ , it is thermal cracking of propane into ethene and methane.

The complete reaction for the reactants is $CH \equiv CH + H_{2} \to {CH}_{2} = {CH}_{2}$ , It is an addition reaction where hydrogen gets attached to alkyne to form alkene.

Complete table is as follows:

Reactants (A)
Products (B) Name of the reaction (C)

${CH}_{3} - {CH}_{3} + {CI}_{2}$
${CH}_{3} — {CH}_{2} CI + HCI$ Substitution reaction

$C_{2} H_{6} + O_{2}$
${CO}_{2} + H_{2} O$ Combustion

${nCH}_{2} = {CH}_{2}$
$[- {CH}_{2} - {CH}_{2} -]_{n}$ Polymerisation

${CH}_{3} - {CH}_{2} — {CH}_{3}$
${CH}_{2} = {CH}_{2} + {CH}_{4}$ Thermal cracking

$CH \equiv CH + H_{2}$
${CH}_{2} = {CH}_{2}$ Addition reaction
