How do I name this ester?

CH3OCOCH2C(Br)2CH2CH2Cl

How do I name this ester?
methyl 5-chloro-3,3dibromopentanoate? This doesn't sound right to me


It is made of methanol and 5-chloro-3,3dibromopentanoic acid I think?

Hey Charco! I was just wondering you know she wrote methyl 5-chloro-3,3dibromopentanoate

I thought it was meant to be in alphabetical order since b comes before c in the alphabet but when your doing it do you also have to look at whats infront e.g. whether it is tri or di etc and then u decide from that so since c comes before d in the alphabet that is why the chloro bit comes first?

this mayb stupid but the general formula for an ester is RCOOR right?so is it correct if the above ester is written as ClCH2CH2C(Br)2CH2COOCH3? also do we just use the RCOOR for ease or is it like a compulsion or rule?because the formula was given as CH3OCO..its the same thing doest follow the general trend but its still correct isnt it?

You are, of course, correct. The bromo should come before the chloro and the multipliers do not have any effect.

For esters the alcohol comes first followed by the carboxylic acid. The way to identify the alcohol is by looking which carbon is single bonded to only ONE oxygen in the ester link
