Which of the given compounds can enhance the efficiency of hydrogen storage tank?
Options
- ALi / P 4
- BSiH 4
- CNaNi 5
- DDi-isobutylaluminium hydride
Correct answer
C. NaNi 5
Step-by-step 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.
