Question

question what is the name of this molecule? ch₃c≡cch₂ch₂ch₃ select the correct answer below: 2 - hexyne 3 - hexyne 2 - hexene 3 - hexene

Explanation:

Step1: Identify the parent chain

The molecule has 6 - carbon atoms in the longest continuous chain, so the parent name is 'hex -'.

Step2: Identify the functional group

There is a triple bond ($C\equiv C$), which makes it an alkyne.

Step3: Number the carbon atoms

Number the carbon atoms in the chain so that the triple - bond gets the lowest number. Starting from the left - hand side, the triple bond is between the second and third carbon atoms. So the name is 2 - hexyne.

Answer:

A. 2 - hexyne
