Q15 / 90 · JEE Main 2023 (29 Jan Shift 1) · Chemistry

Which of the given compounds can enhance the efficiency of hydrogen storage tank?

A
$Li / P_{4}$
B
${SiH}_{4}$
Correct answer
C
${NaNi}_{5}$
D
Di-isobutylaluminium hydride

Solution

Dihydrogen gas is converted into liquid state by cooling to 20K. This would require expensive insulated tanks. Tanks are metal alloy like

{NaNi}_{5}, Ti - {TiH}_{2}, Mg - {MgH}_{2,}

etc. are in use for storage of dihydrogen.

Hence, the correct answer is option: 'C'.
