So I am struggling to name the following two radicals, please excuse the fact that they are not drawn properly.

Radical number 1) HC(O)OC or if you prefer an attempt at the structure H-C(=O)-O=C

Radical number 2) HC(O)CO or if you prefer an attempt at the structure H-C(=O)-C=O

All/any help appreciated
