Answer 1

Answer:

1.In ethyne due to presence of triple bond, electron density is very high so it is more reactive than ethane. Also due to saturation ethane is less reactive than ethyne.

2.Alkenes are relatively stable compounds, but are more reactive than alkanes because of the reactivity of the carbon–carbon π-bond. ... The π-bond in the ethylene molecule is responsible for its useful reactivity. The double bond is a region of high electron density, thus it is susceptible to attack by #electrophiles.

3.Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. ... They make good fuels because their covalent bonds store a large amount of energy, which is released when the molecules are burned (i.e., when they react with oxygen to form carbon dioxide and water).

Answer 2

GIVE REASONS......

1. In ethyne due to presence of triple bond electron density is very high so it's more reactive Than ethane.

2.Ethene is highly reactive compound than ethane because of the presence of double bond.Between it's two carbon atom.

3.Hydrocarbons have high calorific value .they are easily combustible and the reaction is highly exothermic. hence they are excellent fuels.
