2: need help with all. Just doing one and explaining is fine.

3: I don't know how to use VSEPR theory.

4: last two boxes and i need to know how to determine molecular dipole.

7: confused

9: I don't think the lone pair is in the right spot.

10: Just review to make sure I got all the structures.

Thanks in advance!

2. For each of the structures below. Fill in lone pairs to give all 2nd period elements a full octet. For each atom bearing a formal charge, show the charge H3C-CEC N. (CH3)2NH N-H 3. Draw proper Lewis structures and indicate all bond angles using VSEPR theory for the following . H A-CN-C-H H (CH3)2N-CH2 3 2 CH3 H-C-N- OH-O-C=N H 4 Draw three-dimensional structures of each of the following using the wedge-dash notation if needed), and indicate (yes or no) on the line beneath each box whether or not it has a molecular dipolo moment. If it does have a molecular dipole, clearly show its direction with an arrow next to the molecule. CHCI FC-CH CICUCCI H Br Ca CHFBr CUF B Molecular dipole? Name: 5.
