Question

A hydrocarbon A is cracked to make B and hydrogen. Compound C is formed by the addition polymerization of B. To which homologous series do A, B and C belong? alkene alkane B and C A and C A and B A and C

Answer 1

Hint:
Organic chemistry is based on an organic compound. These compounds contain carbon-hydrogen bonds. There are three types of hydrocarbons, Saturated, Unsaturated, and Aromatic hydrocarbon. In chemistry, many times, complex hydrocarbon breaks to make them more useful.

Complete answer:
Firstly, let's take a look at types of hydrocarbon
Saturated hydrocarbon - They contain single bonds between carbon and hydrogen. It is also known as alkanes. Its formula is \[{C_n}{H_{2n + 2}}\] .
Unsaturated hydrocarbon - They contain more than one bond, it may be a double or triple bond compound. Double bond hydrocarbon known as alkenes and its formula is ${C_n}{H_{2n}}$. Triple bond hydrocarbon is known as alkynes, and its formula is ${C_n}{H_{2n - 2}}$.
Cracking - When complex hydrocarbons break into simple hydrocarbons is known as cracking. And say long-chain hydrocarbons break into the simple molecule. The rate of this process depends on catalysts and temperature.
This process can convert alkane to the alkene. So, according to question A must be Alkane that converts into B, which means alkene and hydrogen.
When we do polymerization of B, it will form polyalkene. Thus, C will be polyalkene.
Now, we got
A - Alkane
B - Alkene
C - Polyalkene

Note:Aromatic hydrocarbon - They contain at least one aromatic ring. Polymerization - When monomer molecules react they form the polymer is known as polymerization. Polymer - It is the chain of large molecules.
