Question

Conversion of but-1-yne to butane by sabatier method

Answer 1

But 1 ene contains less number of hydrogen than butane so if we have to add 2 hydrogens to but 1 ene then the double bond breaks and forms single bond resulting to form butane. To do so we have to use hydrogenation I.e. adding of hydrogen:

Ch2=ch-ch2-ch3 + H2 = ch3-ch2-ch2-ch3
