Question

Choose the correct option for the number and type of covalent bonds in a molecule of ethyne.

• A. 4 single, 1 double
• B. 4 single, 0 double
• C. 2 single, 0 triple
• D. 2 single, 1 triple

Answer 1

The correct option is D 2 single, 1 triple

So from the structure of ethyne $(H-C\equiv C-H)$, it can be seen that it has one triple bond and two single covalent bonds. Hence, option (d) is correct.
