Question

Why are certain compounds called hydrocarbons? write the general formula of homologous series of alkanes, alkenes & alkynes and also draw the structure of the first member of each series. write the name of the reaction that convert alkenes into alkanes and also write a chemical equation to show the necessary condition for the reaction to occur.

Answer 1

•compounds made up of only hydrogen and carbon are known as hydrocarbons. they are further divides as saturated and unsaturated...

• alkanes = C n H 2n + 2

alkenes = C n H 2n

alkynes = C n H n

• reaction name is hydrogenation

necessary conditions are catylst nickel ..platinum or paladium
