Question

Determine the number of hydrogen atoms in an alkyne with one carbon–carbon triple bond and 4 carbon atoms.
number of hydrogen atoms: ?

Answer 1

Answer:

There are 6 hydrogen atoms.

Explanation:

The formula for an alkyne that has only one triple bond is as follows:

• CₙH₂₍ₙ₎₋₂

Where n is any natural number greater than 2.

For this problem, n=4. This would mean the formula is:

• C₄H₂₍₄₎₋₂

Thus

• C₄H₈₋₂

• C₄H₆

Thus the answer is 6, there are 6 hydrogen atoms.
