I am desperate to be able to draw the line structurwes of the following molecules:

(1)  2-bromo-2,2-dichloroethanoic acid

(2)  3-methylbutanoic acid

(3)  Ethyl 2,6-diethyl-4,5,6-trihydroxy-3-oxooct-7-enoate

is this last one an Ester? and how do I incorporate all the other components into the line structure of this entire molecule!?

Thankyou

1) Draw the parent chain.

2) Attach your primary functional group.

3) Number the chain.

4) Attach substituents.
