Question

How are methane and ethane prepared from methyl iodide and ethyl bromide?

✓

Answer

When methyl iodide is reduced by nascent hydrogen at ordinary room temperature then methane is formed.
$
CH _3 I +2[ H ] \longrightarrow CH _4+ HI
$
When bromoethane is reduced by nascent hydrogen at ordinary room temperature then ethane is produced.
$
C _2 H _5 Br +2[ H ] \longrightarrow C _2 H _6+ HBr
