Name the pentene compound.


Name the pentene compound.


While naming of the organic compounds, we will follow IUPAC rules. Consider the longest chain of carbons atoms as a parent chain, substituents should be at lowest possible position and the name of the compound should be arranged in the alphabetical order.

Answer and Explanation: 1

We are given the following compound:

It is a disubstituted cyclopentane. According to the IUPAC rules, the substituents should be given the lowest possible locant. If multiple bond are present in the compound, the preference is given that bond and in the given compound, 1 double bond is present, so the priority is given to the ethyl group. Therefore, ethyl group is present at 1 position and methyl group is at 3rd position.

Hence, the name is of the compound is 1-Ethyl-3-methyl pentene
