Compare the bonding in formic acid (HCOOH) with that in its conjugate base formate ion (HCOO). Each molecule has a central carbon atom bonded to the two oxygen atoms and to a hydrogen atom. Draw Lewis diagrams, determine the steric numbers and hybridization of the central carbon atom, and give the molecular geometries. How do the orbitals differ in formic acid and the formate molecular ion? The bond lengths of the CO bonds in HCOOH are 1.23 (for the bond to the lone oxygen) and 1.36 (for the bond to the oxygen with a hydrogen atom attached). In what range of lengths do you predict the CO bond length in the formate ion to lie?
all of the orbital overlaps in NCO ‒---- Which of the following statements is TRUE? Select one: Pi bonds are stronger than sigma bonds. The sp2 hybridization scheme for carbon allows for the formation of two pi bonds. A carbon-carbon triple bond consists of one π bond. Pi bonds can hold 4 electrons: 2 above the bond axis, and 2 below the bond axis. A molecule with the VSEPR class AX4E2 will have a central atom that is sp3d2 hybridized.

I have a question regarding hybrid vs atomic orbitals: 1) What would be the hybridizations of C and O in the molecule H2CO? It asks to draw an electron orbital diagram (with arrows) of all the electrons in C before and after hybridization. 2) Draw a diagram of the H2CO molecule showing the overlap of orbitals between the C and O atoms that make up the sigma (σ) and pi (π) bonds. Which orbitals make up the σ bond? Which ones form the π bond?

Two isomers share the molecular formula C3H4. In Structure A two ofthe carbon atoms are sp hybridized and one carbon atom is sp3 hybridized. In Structure B, two of the carbon atoms are sp2 hybridized and one carbon atom is sphybridized. b)Draw “3D”-looking structures on paper, make a sketch of each of the isomers. (This should be a sketch of themolecules, not diagrams of overlapping orbitals!) Your drawing should show thecorrect molecular geometry around each carbon atom. [HINT: NEITHER of thesemolecules is planar!!! To draw them correctly, you will have to consider why!]
