X and Y are two compounds made up of C and H. In X, the number of hydrogen is two more than twice the number of carbon. On the other hand in compound Y, the number of hydrogen is exactly twice the number of carbon. Identify which one is saturated and which one is unsaturated.

Dear Student,

Compound X , Number of Hydrogen = 2 + 2Number of carbon atom

General formula of compound = CnH2+2n

Compound Y , Number of Hydrogen = 2Number of carbon atom

General formula of compound = CnH2n

Compound X is saturated compound.

For example: take n = 2
So the formula of compound X becomes = CnH2+2n = C2H2+2X2 =C2H6
This is the formula of ethane and it is saturated hydrocarbon


formula of compound Y = CnH2n =C2H2X2 =C2H4


This is the formula of ethene and it is unsaturated hydrocarbon


 

  • 1
X is saturated and Y is unsaturated because:-
case 1
for unsaturated hydrocarbon CH2n or CH2n-2 
case 2
for saturated hydrocarbon CH2n+2
according to question first condition states the case 2 and second condition states case 1
