Question

multiple choice 2 points provide the proper iupac name for the alkene shown below. 1 - bromo - 6 - methylcyclohexene 6 - bromo - 1 - methylcyclohexene 6 - bromo - 1 - methylcyclohex - 2 - ene 1 - bromo - 6 - methylcyclohex - 2 - ene

Explanation:

Step1: Determine the parent chain

The parent chain is cyclohexene (a six - membered ring with a double bond).

Step2: Number the ring

Number the ring so that the double bond gets the lowest possible numbers. For cyclohexene, the double bond is between carbon - 1 and carbon - 2.

Step3: Locate substituents

The bromine atom (\(Br\)) is on carbon - 6 and the methyl group (\(CH_3\)) is on carbon - 1.

Step4: Write the name

According to IUPAC rules, we list the substituents in alphabetical order (bromo comes before methyl). So the name is 6 - bromo - 1 - methylcyclohexene.

Answer:

6-bromo-1-methylcyclohexene
