Calculate formal charge for each atom. Circle the most favorable structure, if any. a) COBr2 b) CH3CONH2 (connectivity as shown below) нсин c N 4. For each of the following, draw all bond dipoles on the first structure, then draw the net dipole on the second structure. If non-polar, write "no net" Bond :0: dipoles OLL-O- Net dipole o=0 ex: 5. The following are the two possible Lewis structures for CH2F2. Will both of them have the same dipole moment? Draw bond dipoles, net dipole direction and explain your answer. Е н. Ен C=C HF C G FH

Answer 1

Number (No. of Valence | I elections I on Atom Formal Charge Number of 1 lections - of bonds t non-bonding bonds elections Acom Valence elections :N-C30: N=C=ö <> NEC-Ö: 5-(3+2)=0 5-(2+4)=7 6-(2+4)=100 6-(1+6) - FI 4-(4+0) = 0 5-(1+6) = -2 6-(3+2) - 4-(4+0)=0 4-(4+0) = 0 as it has Structure ② is most favourable structure charge on only one atom. Also, the negative change is on oratom mose electronegative than station which Stable. which is makes it more
