What is the IUPAC name for a molecule with a bromine and an ethenyl group on a cyclopentane ring in a 1,2 position?

The molecule contains a five-membered carbon ring, which is a cyclopentane ring.

There is a bromine atom (Br) attached to the ring.
There is an ethenyl group ($-\text{CH}=\text{CH}_2$) attached to the ring.

Number the ring carbons to give the lowest possible locants to the substituents. If there's a tie, prioritize alphabetically.
If we assign the carbon with bromine as C1, the ethenyl group would be at C2 (1,2-substitution).
If we assign the carbon with the ethenyl group as C1, the bromine would be at C2 (1,2-substitution).
Since both options result in 1,2-substitution, we prioritize alphabetically. "Bromo" comes before "ethenyl". Therefore, the carbon with bromine is C1, and the carbon with the ethenyl group is C2.

List the substituents in alphabetical order, followed by the parent ring name.
The name is 1-bromo-2-ethenylcyclopentane.
