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 CH, Add formal charges to CH . Note the presence of the lone pair.
