Question

Ethyl alcohol to Ethane.

✓

Answer

When concentrated sulphuric acid is added to ethyl alcohol, it causes dehydration to give ethene. Ethene reacts with hydrozen in presence of $Ni$ to give ethane.
$
C _2 H _5 OH \xrightarrow[170^{-}]{\text {Conc } \cdot H _2 SO _4} CH _2= CH _2+ H _2 O
$
$
CH _2= CH _2+ H _2 \xrightarrow[300^{\circ} C ]{ Ni } CH _3- CH _3
