Answer 1

An unsaturated hydrocarbon having a triple covalent bond has 50 hydrogen atoms in its molecule. The number of carbon atoms in its molecule will be 26.

Explanation:

The general formula for unsaturated hydrocarbons with triple bond, is C_nH_2n-2. Where 'n' is the number of atoms in one molecule. If the number of hydrogen atoms in its molecule is 50, then the number of carbon atoms should be 26 (2n-2 = 50; therefore, n = 26).
