1. A molecule which has C, N, O and H has no formal charge on any...
Assign formal charges to the atoms in these three structures (only necessary for atoms with nonzero formal charge). Do not add or delete bonds or electrons, except where indicated. Assume that all unshared valence electrons are shown but overall charges are not. Add formal charges to CH3 Add formal charges to CH3 . Note the presence of the lone pair. Add a lone pair to NH3. Add a formal charge, if applicable. Which atoms have a complete octet? The C in CH3 without the lone pair. The...

Write name of the molecular geometry for each of the following molecules. a. A molecule with the central atom surrounded by three atoms and one lone pair. b. A molecule with a central atom surrounded by two doubly-bonded atoms. c. A molecule with a central atom surrounded by two singly-bonded atoms and two lone pairs....
2. (4 marks) A molecule with molecular formula CH2N2 has a C-N-N bond angle of 180° and an H-C-H bond angle of 120°. Draw the Lewis structure of this compound that is consistent with these bond angles and also satisfies the octet rule. Show all lone pairs in this structure using the proper dots (*) and determine the formal charges on all atoms. Indicate the formal charges on atoms only if they are not zero. If more than one resonance...
