Propene reacts with hydrogen in the presence of catalyst and forms .

The correct options are
A nickel
C propane
$\bullet$ An unsaturated hydrocarbon is converted to a saturated hydrocarbon by the addition of hydrogen atoms in the presence of nickel catalyst.

$\bullet$ The hydrogen atoms are added to the carbon atoms having a double bond or a triple bond between them.

$\bullet$ For example, prop-1-ene is converted to propane as shown below.
${\mathrm{CH}}_3-\mathrm{CH}={\mathrm{CH}}_2\left(g\right)+H_2\left(g\right)\underset{}{\overset{\mathrm{Ni}}{\to }}{\mathrm{CH}}_3-{\mathrm{CH}}_2-{\mathrm{CH}}_3\left(g\right)\mathrm{Prop}-1-\mathrm{ene}\mathrm{Hydrogen}\mathrm{Propane}$
