Question

why acetylene is more reactive than ethene while ethene is more reactive than ethane​

Answer 1

Ethyne is more reactive than ethene because it has two π-bonds which makes it weaker than ethene…A support to my answer is the acidic nature of ethyne .In water the ethyne readily donates its H-atom . ... The single bond is the most stable ,hence the least reactive because the two electrons are more comfy in their orbits.
