what is the lewis structure of (HO)2CO?

………………..OH
………………….C=O
………………..OH

on the top O of OH, it will have 2 nonbonding pairs of electrons
on the bottom O of OH, it will have 2 nonbonding pairs of electrons
for the O attached to the C atom with a double bond also has 2 nonbonding pairs of electrons
hard to draw here
