Determine whether each compound is a hydrocarbon.(a) CH2O(b) CH4(c) C6H6(d) C2H7N

Solution 34P:

Here, we are going to determine whether the given compounds are hydrocarbon.

Step1:

Hydrocarbons are the compounds of carbon and hydrogen only. Hydrocarbons are of different types. Depending upon the types of carbon-carbon bonds present, they can be classified into three main categories –

(i) saturated

(ii) unsaturated and

(iii) aromatic hydrocarbons.

Saturated hydrocarbons contain carbon-carbon and carbon-hydrogen single bonds. Unsaturated hydrocarbons contain carbon-carbon multiple bonds – double bonds, triple bonds or both. Aromatic hydrocarbons are a special type of cyclic compounds.

Step2:

1. CH2O contains oxygen along with carbon and hydrogen. So, it is not a hydrocarbon.
2. CH4 contains carbon and hydrogen only. So, it is a hydrocarbon.
3. C6H6 contains carbon and hydrogen only. So, it is a hydrocarbon.
4. C2H7N contains nitrogen along with carbon and hydrogen. So, it is not a hydrocarbon.
