Question

Write a balanced chemical equation for each of the following:
Preparation of methane from iodomethane.

Answer 1

Methane is prepared from iodomethane by heating with HI and red phosphorus in sealed tube.
$C{H}_3-I+HI\underset{\text{150 degree, pressure}}{\overset{P}{\to }}C{H}_4+I_2$
In this reaction, iodomethane is reduced to methane.
