What is the name of the compound shown? Use von Baeyer rules: bridges in decreasing order in the brackets, numbering from a bridgehead.

  1. A1-methylbicyclo[2.2.2]octane
  2. B2-methylbicyclo[2.2.2]octane
  3. C1-methylbicyclo[3.2.1]octane
  4. D4-methylbicyclo[2.2.2]octane

Answer: A

The compound is 1-methylbicyclo[2.2.2]octane. Numbering begins at a bridgehead, and the methyl is on a bridgehead, so it gets the lowest possible locant, 1; the two bridgeheads are equivalent and the other end would be C4.
