i know y the ethyl is before the methyl but which is carbon 1 and which is 2? and why?

 

[joonkimdds]

answer is 1-ethyl-2-methyl cyclohexane.
I forgot why.

The carbon which the methyl side chain is C-1. Name clockwise.
2-ethyl-1-methyl cyclohexane.

 

[tranv117]

its 1-ethyl,2-methylcyclohexane. Both are alkanes so no particular preference in naming. But e is before m so go with ethyl 1st.

here since you have no point of difference, need to name it based on

alphabetical order.So ethyl comes first.Thus u start with ethyl.
1-ethyl-2methycyclohexane​

Nope clockwise and counterclockwise are the same thing, you can just turn the moleculearound and then what lol. When all numbers are the same we follow the alphabet with the carbon that has the lower alphabetical substituent on it getting naming precedence.
