16. How many sigma and pi bonds are in the molecule below? Give the hybridizations and the bond angles of the three carbon atoms and the nitrogen atom indicated in the molecule. Give the name of the geometry for the d three carbon atoms. No geometry is implied in the Lewis C structure shown. (13 pts total) H HH H-C=C-C-CEN: # of sigma bonds: # of pi bonds: 3 H - C -H H a b hybridization: a. se ; c. _ d . _ bond angle: a. name of geometry around the C atoms: a. ; b. ; C. 17. A C-O bond has a length of 143 pm and a dipole moment of 2.9 D. Calculate the magnitude of the charge separation (in units of elementary charge). (4 pts) XD 18. Explain why 1,2-dichloroethene, CHCI=CHCI, has no net dipole moment even though the C-CI bonds are polar. (2 pts) They have no dipole C = C - H movement because they H' CI cancel each oth out , 2
