propan-2-ol,  CH3CH(OH)CH3 Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons and any formal charges if necessary.

Draw Lewis structures for each of the following ions. One atom in each ion has a formal charge that is not zero.Determine which atom it is, and what the formal charge is. (a) the C2H5 anion; (b) the CH3O cation; (c) the CH6N cation;(d) the CH5O cation; (e) the C3H3 anion (all three H atoms are on the same carbon)

Q. 9a) Provide additional resonance structures for the following species. Remember to show lone pairs & formal charges where applicable + [ :N=N-F: +→ [:0-C!-O: → Q. 9b) Draw the Lewis Structure for NCCH2CO2NHCH3, determine the number of sigma bonds & the number of pi bonds present, and indicate the bond angle value around each carbon atom, each nitrogen atom, and each oxygen atom.

Draw the contributing structure indicated by the curved arrow(s). Show all valence electrons and all formal charges

Draw the best Lewis structure for the linear C ion, including all lone pair electrons and non-zero formal charges.

Unshared, or lone, electron pairs play an important role in determining the chermical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. The number of unshared pairs at atom a is The number of unshared pairs at atom b is HyC CH The number of unshared pairs at atom e is The number of unshared pairs at atom a is The number of unshared pairs at atom b is HC CH The number of unshared pairs at atom e is
