(Solved): One of my first orgo assignments coming up and want to get in some practice questions we were given ...

Assignment 1 1. Complete the following tasks for the molecule CH?O2 a) List the number of valence electrons for each of the atoms in this molecule b) Draw the Lewis Structure of CH?O2 (the C is the central atom) c) Identify each line in the Lewis structure as a sigma bond or a pi bond d) Identify the orbitals involved in forming each of the bonds e) Identify the hybridization of each atom in the molecule 2. For the molecules below... i. Re-draw the molecule as a skeletal structure, including lone pairs II. Identify the hybridization of each atom in the structure ill. Specifically label any bond angles that are expected to be either 120? or 180° H b) H-C-H Br H "H -H H-CIC C -C-H 3. The structure below indicates where carbon atoms are located and explicitly shows all atoms that are not C nor H. It also includes any formal charges present on any of the atoms in the molecule. Re-draw the structure as a Lewis structure which includes all carbon atoms, hydrogen atoms and all lone pairs. 4. In the structure below all atoms, bonds and lone pairs are shown. Identify any atoms which have a formal charge, calculate each individual formal charge and then the overall formal charge on the molecule H :0: 5. Re-draw the structure below including all lone pairs and then determine the formula including the overall charge on the structure. OH OH
