• Problem Set 3 - Solutions

2

• All O are sp2, molecule is bent with OOO angle
  120o. Molecular orbitals resemble those of the
  allyl anion.

3

• CN-
• C,N are sp hybrid, lone pair on each, linear ion.

4

• BF3
• B is sp2 with empty pz orbital, molecule is
  trigonal planar.

5

• OCO
• O are sp2, C is sp, linear molecule.

6

• C2H3-C1?N
• C1 is sp, C2 is sp3, N is sp with lone pair.
• Tetrahedral geometry at C2, linear at C1.

7

• C2H3N?C1-
• C1, N are sp, C2 is sp3.
• C1 has a lone pair. Molecule is tetrahedral at
  C2, linear at N.

8

• BH4- B is sp3, tetrahedral molecule.

9

• Plane of CC and CO are at 90o. C-C-O,
  sp2-sp-sp2. This is closely related to allene,
  except that you have replaced one CH2 with
  oxygen. In CO2 you replace both.
