    1. The problem statement, all variables and given/known data

    Name this molecule


    2. Relevant equations

    Naming cycloalkanes:

    1) The functional groups should receive the lowest carbon number.
    2) Any substituents are then assigned carbon numbers.

    3. The attempt at a solution

    Following the above two rules, shouldn't the molecule therefore be named 1-methyl-3-chlorocyclobutane?

    The key however says 1-chloro-3-methylcyclobutane. Please advise.

    Oops. Realized that halide substituents are treated the same as functional groups.
