Question

An unsaturated hydrocarbon us a hydrogen-carbon compound with ___​

Answer 1

An unsaturated hydrocarbon is a hydrogen-carbon compound with one or more double or triple bonds of carbon-carbon atoms.

Explanation:

Generally hydrocarbons are compounds formed entirely by combination of carbon and hydrogen molecules. Hydrocarbons are classified as saturated and unsaturated hydrocarbons. A saturated hydrocarbons are those where the hydrogen-carbon molecules are formed with carbon-hydrogen single bond.

They are the simplest of hydrocarbons and the hydrogen atoms are dominant in them. While in unsaturated hydrocarbons, the number count of hydrogen atoms will be less to form bonds with carbon. So in unsaturated hydrocarbons, more number of carbon-carbon double or triple bonds are observed and less number of single bonds of C-H will be present.

Answer 2

Answer:with double or triple carbon carbon bond between it's corresponding hydrocarbon or organic compound thus gives rise to alkene and alkyne
