Why does ethene have different chemical properties from decane and hexane?

Answer 1

It is a completely different compound with its own unique chemical and physical properties. Ethene conatins a C=C double bond and is an unsaturated hydrocarbon, decane and hexane are alkanes and conatin only single C-C bonds

Answer 2

Ethene is an unsaturated hydrocarbon with a double bond, while decane and hexane are saturated hydrocarbons with only single bonds. The presence of double bonds in ethene leads to it being more reactive than decane and hexane. Additionally, the shorter carbon chains in ethene result in different physical and chemical properties compared to the longer carbon chains in decane and hexane.
