2 lone pairs on the oxygen molecule are in unhybridized p orbitals.
Buy ‘solomon&fryhle’’s book on organic chemistry (INR700). It takes 6-8 days to read it’s 1090 pages provided you’ve read your board’s textbook before.

3 double bonds corresponds to 6 pi electrons , in addition to it there are two lone pairs with oxygen which are counted as pi electons , therefore 6+4=10

i think its 8 ,  3 double bonds =6pi electrons and 1l.p of oxygen is delocalised so that the compound is aromatic.
The other is in sp2 hybridised orital
