Monospiro hydrocarbons with two monocyclic rings are numbered consecutively starting in the smaller ring at an atom next to the spiro atom, proceeding around the smaller ring back to the spiro atom and then round the second ring.

Example:

spiro[4.5]decane
not spiro[5.4]decane

Hi, are there any rules on numbering carbon substituents that are not apart of the main ring? For example if there were two methyl groups, each on a different carbon, how do you number each one?

Hi James
Can you explain to me in details the mystery behind the nomenclature of bicyclic compounds in this site? I would be very glad to hear your reply as I need to send it to someone (@QuestionCookie) on https://chemistry.stackexchange.com as an answer to his/her question on “R/S configuration of bridging carbon in bicyclic system” within 10 hours in order to get a bounty worth +50 reputations from him/her
Thanks
Satyajay Mandal

for example, how would i name something like this
6-endo-bromo-8-anti-isobutyl-1,3-exo-dimethylbicyclo[3.2.1]octane
from a configuration diagram

In reply to Mrunal. Not sure I understand the first part of your question. Yes, 2-fluorobicyclo[2.2.2]octane is chiral and will exist as a pair of enantiomers.
