Question

what is covalency of carbon in etane ,ethene are ethyne

Answer 1

in ethane the carbon atoms share one electron

in ethene the carbon atoms share two electrons

in ethyne the carbon atoms share three electrons

Answer 2

The covalency of carbon in ethane , ethene and ethyne is four , four three respectively.

Explanation:

• Each carbon has 4 hands, so it's covalency is four.

• C2H4 is ethylene or ethene is a colourless hydrocarbon. The carbon has valency of four because the molecule has 4 H atoms bound to a couple of C atoms which are related by double bonds.

• In ethyne the carbon atoms shares 3 electrons
