Question

Name structure with a valid IUPAC name

Answer 1

7-bromo-4-hydroxl-2-octene

Answer 2

@oOKawaiiOo Wow thank you! Do we not account for the methyl groups?

Answer 3

oh shooottttt.......my bad!! let me rename it!!!

Answer 4

7-bromo-4-hydroxl-2,3,5-trimethyl-2-octene

Answer 5

You have to account for anything off of parent chain.

Answer 6

oo nice! and why is it TRImethyl and not like PENTAmethyl (not sure if it makes sense, new to learning this)

Answer 7

@oOKawaiiOo

Answer 8

There are 3x methyl groups off of the parent chain (longest carbon chain counted), so you call it Tri-

I was a chem major :)

Answer 9

Oh yes okay I see where i went wrong here! I was going crazy over those methyl groups. Would you mind assisting with one more? I got : 2-chloro-4-Fluro-3,3-dimethyl phenol. Except I'm 100% certain if i started my numbering in the right place @oOKawaiiOo

Answer 10

Im not 100%**

Answer 11

In this case.....the hydroxl take priority (so you are on the right track)

Answer 12

OH ok! So the came I up with would be fine? @oOKawaiiOo

Answer 13

im looking at it now,......give me a few minutes

Answer 14

1-fluoro-2,2-dimethyl-3-chloro-4-cyclohexanol

Answer 15

The reason why Fluorine is #1 and not #4 is because you want the numbers to be the lowest as possible.

For example
1-X-2-Y-3-Z ....... 1+2+3 = 6
3-X-3-Y-3-Z ........3+3+3 =9

6 is lower in value than 9, so 1-X-2-Y-3-Z takes priority over 3-X-3-Y-3-Z

Answer 16

hmm I somewhat understand. except I'm a little confused about the example

Answer 17

I'm still shaky with the numbering

Answer 18

How would you name this?
