In the preparation of alkanes by the reduction of alkyl halides, we observe the following reaction: R-X + 2H --------> R-H + X2 Catalyst- Zn+HCl X=Halogen, R=Alkyl group Can you explain the mechanism of this reaction?

There is no any well behave mechanism for show graphically show.But actually Zn/HCl produces nascent hydrogen .This nascent hydrogen then reduces Alkyl halide to Alkane.(*A hypothetically you can think this as radical type mechanism)
