Question

Complete the following reaction: R-CC-R’ + H2 —–> _______

(a) R-CH-CH-R’

(b) R-CH2-CH3

(c) R-CH2-CH2-R’

(d) All of the mentioned

This question was posed to me in examination.

This interesting question is from Catalytic Hydrogenation in chapter Hydrogenation of Unit Processes

Answer 1

Correct choice is (c) R-CH2-CH2-R’

To explain I would say: The reaction is hydrogenation reaction and is as follows:    R-CC-R’ + H2 —–>R-CH2-CH2-R.
