tag all the carbon atoms with pi bonds in this molecule. if there are none, please check the box below.\nthere are none.

Answer

Explanation:

Step1: Recall bond - type knowledge

Pi bonds are present in double and triple bonds. Single bonds are sigma bonds only.

Step2: Analyze the given molecule

The molecule has a triple - bond ($C\equiv C$). In a triple - bond, there are 2 pi bonds and 1 sigma bond. The carbon atoms involved in the triple - bond ($C\equiv C$) have pi bonds.

Answer:

The two carbon atoms involved in the triple - bond ($C\equiv C$) should be tagged.
