Question

Which of the following compounds is unsaturated hydrocarbon?

• A. Diagram
• B. Diagram
• C. Diagram
• D. Diagram

Answer 1

The correct option is B Diagram

$\text{Defining unsaturated hydrocarbon:}$

Unsaturated hydrocarbons are the
compounds containing only $C,$ and there is either $C=C$ or $C\equiv C$ bond or both
in the structure.

$\text{Analysing the options:}$

$\text{Options (A) and (B):}$
The compounds given in options (A) and (B) are unsaturated, but not hydrocarbons. This is because they contain oxygen and nitrogen atoms respectively along with carbon and hydrogen.

$\text{Option (c):}$

It is a saturated hydrocarbon because it contains only carbon-carbon single bonds.

Diagram

$\text{Option (d):}$

It is an unsaturated hydrocarbon because it contains only carbon and hydrogen atoms as well as $C=C$ in its molecule.

So, option (d) is the correct answer.
