Answer:

12

Explanation:

alkyne formula is CnH2n-2

heptyne = 7

The total number of hydrogen atoms in a molecule of heptyne is twelve (12).

What is heptyne?

Heptyne belong to alkyne family with one triple bond and the molecular formula can be determined as follows;

CₙH2ₙ-2

Heptyne contains 7 carbons

C7H[2x 7 - 2] = C7H12

Thus, we can conclude that, the total number of hydrogen atoms in a molecule of heptyne is twelve-12.
