Question

total valence electrons. has 1. The nitrite ion NO2 2. Draw the Lewis structure including nonbonding e- pairs for dibromomethane CH2Br2. There valence electrons. are 3. Using methane (see Procedure) as an example, draw CH2Br2 so that its shape is apparent Include nonbonding e- pairs where relevant. 4. For CH2Br A. The e- domain geometry is B. The molecular geometry is C. This molecule is a) polar b) nonpolar

Answer 1

0 Given Noa Nitrogen (n) Group number = number of Valence electrons = 5. O Group = number of Valence electrons = 6 A Total valence electrons in ng is 55+266) + (+1) = 18 electrons. Total Valence electrons = 18 ② CH BY c Valence electrons = Group number = 4 By Valence electrons = Group number => H Valence electrons = Group hemeber = 1 .: Total Valence electrons = 4+201)+26 = 20 electronsa Scanned with CamScanner
