What would be the name of this Ester. Is the main functional group the ester is the suffix is -oate?

The structure is here:Name:  image.jpg

I’ve tried ethylbromopropanoate?? But will the functional group need any numbers assigned to it? I’m a bit confused ...

How do you know it’s 3 bromo ?? Why do you count the carbons from where the carboxylic part starts and not from where ethyl group starts?

In carboxylic acids the carbonyl group is always assigned #1

But this is an ester which also has an alkyl group attached so why isn’t that group also numbered? I don’t get why the carboxylic acid part is looked at separately.

In esters there are two carbon chains and they are named separately.

1. moiety from alcohol + moiety from acid
