Question

What is an unsaturated hydrocarbon with a triple bond and two carbons?

Answer 1

`"An alkyne..........."`

Explanation:

And the simplest alkyne is `"acetylene"`, `H-C-=C-H`; this has two degrees of unsaturation; i.e. there are 4 hydrogens less than the corresponding alkane formula, that of ethane, `C_2H_6`.
