I don't understand why the ester link in the solutions is OCO instead of the normal COO? Thanks in advance +1

OCO just means there's an oxygen on the left, bonded to a carbon on the right, and the carbon on the right is further doubly bonded to oxygen.

or O-C=O
as for why it's like that, OCO DOES make it clearer; with COO, you have to recognize that it's an ester group

I dunno, it seems to me that it is bonded like -O-C-O-, but I reckon COO would still be accepted don't you reckon?

Certainly; I'd still write COO personally as I'm used to thinking of esters as acid derivatives.
