prioritizing naming

Postby Dahriel Aron 3A » Wed Mar 02, 2016 2:21 pm

If there are 2 substituents that are the same length apart, which would get prioritized for the lower number in naming: chloro or ethyl? or chloro or methyl?

chloro because if its the same distance, you number alphabetically

All alkyl and halogen groups have the same rank. Try to get the lowest possible number first, and ONLY if there is a tie, give the lower number to the alphabetically-first group (bromo < butyl < chloro < ethyl etc)
