Question

Reduction of 1-decyne to decane requires how many equivalents of hydrogen gas?

Answer 1

The reduction of 1-decyne to decane requires 5 equivalents of hydrogen gas. This is because 1-decyne has one carbon-carbon triple bond that needs to be reduced to a single bond, and each triple bond requires 2 equivalents of hydrogen for reduction. Since 1-decyne has one triple bond, it requires 2 x 1 = 2 equivalents of hydrogen. Additionally, 1-decyne has 10 carbon atoms and each carbon atom requires 1 equivalent of hydrogen for reduction, so 10 x 1 = 10 equivalents of hydrogen are needed. Therefore, the total number of equivalents of hydrogen gas required is 2 + 10 = 12 equivalents.
