The bonds present in 1,2-ethylenedicarboxylic acid can be explained if carbon undergoes sp2 hybridized carbon in the background material (check attach file) for this experiment it is clear that this scheme allows for the formation of 3 σ and 1 π bonds.
Create a similar energy level diagram to explain the hybridization of boron in the molecule boron trifluoride, BF3, which exhibits trigonal-planar molecular geometry and bond angles of 120°.
