Question

What are alkenes and alkynes used for?

Answer 1

Hint : Alkenes and alkynes are organic compounds. Organic Compounds are a huge group of chemical compounds in which one or more carbon atoms are covalently attached to atoms of other elements: hydrogen, oxygen, or nitrogen.

Complete Step By Step Answer:
An Alkene is an unsaturated hydrocarbon with at least one double bond between carbon and carbon. Olefins are a term used to describe alkenes.
The uses of Alkenes are:
$1)$ Manufacturing of plastics such as polythene for buckets, pots, and sacks, etc.
$2)$ The manufacturing of Polystyrene is a kind of plastic used to make car battery cases and refrigerator parts.
$3)$ Ethane$ - 1,2 - $diol is used as an anti-freeze in automobile radiators.
$4)$ Production of ethanol and terylene, which is a synthetic fibre.
$5)$ Making an anti-knock device for automobile engines.
$6)$ Production of plastic and polypropene for ropes and packing materials.
$7)$ Manufacture of propanol, which is a chemical that is used to make acetone.
$8)$ Fabrication of acrylic fibres.
An alkyne is a hydrocarbon which is unsaturated and has at least one triple bond between carbon and carbon.
The uses of Alkynes are:
$1)$ Ethyne is most often used to produce organic compounds like ethanoic acid, ethanol, and acrylic acid.
$2)$ Alkyne is also used to make polymers and the raw materials for them. Vinyl chloride, for example, is the primary ingredient for PVC, and chloroprene is the primary ingredient for synthetic rubber neoprene.
$3)$ Ethyne is used to make a range of various organic solvents.
$4)$ Alkynes are widely used to chemically ripen fruits and vegetables.

Note :
 Hydrocarbons with double or triple covalent bonds between adjacent carbon atoms are known as unsaturated hydrocarbons. The expression "unsaturated" refers to the possibility of adding additional hydrogen atoms to a hydrocarbon to make it saturated (which means consisting of all single bonds).
