Numbering of Substituents

Postby Khachik_Hmayakyan_2E » Sat Mar 11, 2017 10:30 pm

On page 70 of the introduction to organic chemistry book, why is the compound named 3-chloro-1-ethyl-1-methoxycyclohexane instead of 1-chloro-3-ethyl-3-methoxycyclohexane. Alchabetically the first substituent chloro should get the higher number shouldn't it?
Is it because the oxy-substituent is given priority in the numbering?

Yes, the oxy-substituent is the one that gets highest priority in this compound.
