Question

Can someone pleas help I have this assignment and the only question I cannot figure out is to describe the hybridization of all the covalent bonds in oxalic acid? and label those bonds as sigma or pi bonds?

I have determine that oxilic acid formula is HO_2CCO_2H and its compound formula is C_2H_2O_4

Answer 1

disregard, I found the answer

Answer 2

The structure of oxalic acid is shown at:

(Broken Link Removed)

Each carbon atom is connected to 3 other atoms (1 double and 2 single bonds). That is sp^2 hybridization.
The two double bonded oxygen atoms are also sp^2 hybridized (1 double bond and 2 nonbonding electron pairs on each)
The two oxygen atoms that are bonded to hydrogens are sp^3 hybridized (2 bonding and two nonbonding pairs each)
The 2 hydrogen atoms are not hybridized.

NOTE: You need to copy the above structure and fill in the nonbonding electron pairs to see the Lewis structure on which hybridization is based.
