Question

Draw the product of the hydrogenation of 2-butyne. draw all hydrogen atoms.

Answer 1

Product:

                     H    H
                     |      |
CH3 - CH2 - C - CH
                     |      |
                     H    H

Explanation:

This is a typical hydrogenation of alkynes. Two of the bonds of the triple bond split and four hydrogen atoms are addet to the molecule, two to each carbon that were bonded by the triple bond.

Answer 2

The product of hydrogenation of 2-butyne is $\boxed{{\text{butane}}\left( {{{\text{C}}_4}{{\text{H}}_{10}}}\right)}$

Further Explanation:

Hydrogenation:

The chemical reaction which occurs between hydrogen molecule and any other compound is called hydrogenation. It occurs generally at high temperatures and in the presence of catalysts such as nickel, platinum or palladium. This reaction reduces the multiple bonds to the single bonds in hydrocarbons. It is used in many applications as food industry, petrochemical industry, and pharmaceutical manufacturing industry.

The general reaction for hydrogenation of alkenes is,

 ${\text{RCH = C}}{{\text{H}}_2}{{\text{H}}_2}\to {\text{RC}}{{\text{H}}_2}{\text{C}}{{\text{H}}_3}$

Here, double bonds present in alkene get converted to single bonds and results in the formation of alkane.

Similarly, the triple bonds present in alkynes get reduced to single bonds and alkane is formed. (For reaction, refer to the attached image)

The hydrogenation of 2-butyne results in the formation of butane. The triple bonds in 2-butyne gets converted to single bonds by hydrogenation reaction. (Refer to the image attached)
