Preparation of diborane involves the oxidation of sodium borohydride with iodine. How many moles of diborane will be obtained from 10 moles of sodium borohydride?

Text Solution

Verified by Experts

The correct Answer is:
`5`
Chemical reaction
`2NaBH_(4)+I_(2)tounderset("Diborane")(B_(2)H_(6))+2Nal+H_(2)`
From reaction stoichiometry,
2 mol `NaBH_(4)=1"mol"B_(2)H_(6)`
`:.` 10 mol `NaH_(4)=5"mol"B_(2)H_(6)`
