(B) Ni + P
(C) Pt + halogen
(D) Pt + charcoal

Answer 1

Option A is the correct answer to this question

Answer 2

Answer:

(A) Pd + Pt

Explanation:

In heterogeneous catalyst reaction we generally used Lindlar's catalyst.

Heterogeneous catalyst is the catalyst used in the reaction in which reactant ,product and catalyst are in different state of matter.

Lindlar's catalyst is a mixture of palladium along with the platinum. It is used to covert the alkynes to alkenes. The required condition for the reaction is pressure must be 1 atm.

So,as per the discussion option (A) is correct.
