The answer for B. is
4-ethyl-7-methyl-2-octene. Could someone explain why.
I keep getting 4-ethyl-3,7-dimethyl-2-octene.
THANKS
Homework Answers
ANSWER:
(a) Name of the compound is:
Here, you can see that the parent chain is of six carbon and branching (methyl) at the fourth carbon and functional group (alkene) starts at second carbon. That why name of alkene is (E)-4-methylhex-2-ene.
(b) Name of the compound is:
You write name of the alkene is (Z)-4-ethyl-3,7-dimethyl-2-octene only. I think answer given is wrong.
Add Answer to:
The answer for B. is
4-ethyl-7-methyl-2-octene. Could someone explain why.
I keep getting 4-ethyl-3,7-dimethyl-2-octene.
