H. H :0: H-C -H- H :0 Lactic acid

Draw the Lewis structure of methanethiol (CH₂SH) and then choose the appropriate pair of molecular geometries of the two central atoms. Your answer choice is independent of the orientation of your drawn structure.

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?

(a) Using the molecular orbital model, write the valence electron configuration for CN and use it to calculate the bond order. Is the species paramagnetic? Bond order = Paramagnetic? (b) Using the molecular orbital model, write the valence electron configuration for CO and use it to calculate the bond order. Is the species paramagnetic? Bond order = Paramagnetic?

(a) Describe the hybridization of the central atom of a molecule with a see-saw shape. (b) Describe the hybridization of the central atom of a molecule with a trigonal planar shape. (c) Describe the hybridization of the central atom of a molecule with a trigonal bipyramidal shape.

2) a) Consider the following molecule . Given what you have learned about hybridization theory, draw an image or images explaining the bonding situation in this molecule. I want you to draw out all of the orbitals, hybrid orbitals and how they overlap to form the bonds in the molecule. Indicate the % s or p character in the given atomic and hybrid orbitals. Which C-C bond or bonds are the longest? In a paragraph or so explain the image or images you just drew. b) Lastly, consider the molecule below. Indicate the Molecular formula, the molar mass, label the hybridization of each atom except for hydrogen, indicate any chiral centers with a *, which bond or bonds are the shortest, identify by name of each functional group with an arrow pointing to the group.
