  1. Name the compound A,B & C
  2. write the equation for the convsion of A to B.name the type of reaction

1. Compound A Ethene C2H4

2. Compound B Ethane C2H6

3. Compound C 1-Chloroethane C2H5Cl

 

2. A to B ---Reduction reaction or hydrogenation reaction

  B to C --- Substitution reaction

 

Organic compound A of molecular formula C2H4 is ethane on reduction gives compound B of molecular formula C2H6 ethane. This is a reduction or hydrogenation reaction.

1. A ---------> Ethene  CH2 = CH2

  B ----------> Ethane CH3 - CH3

  C ----------> Chloroethane CH3 - CH2 - Cl

2. CH2 = CH2 + H2 --------CatalystNi / Pd----------> CH3 - CH3

This reaction is called Addition Reaction.

Also known as Hydrogenation.

This reaction is used in industries to convert Vegetable oil (unsaturated compound) into Vanaspathi Ghee (saturated compound).

1. A is Ethene ----> CH2 = CH2

B is Ethane ----> CH3 - CH3

C is Chloroethane ----> CH3 - CH2 - Cl

2. CH2 = CH2 + H2 ----- Ni/Pd (as catalyst) -------> CH3 - CH3

This Reaction is known as ADDITION REACTION.

This process is also known as HYDROGENATION.

This process is used in industries to convert VEGETABLE OIL (UNSATURATED HYDROCARBON) into VANASPATHI GHEE (SATURATED HYDROCARBON).
