Answer: See below

Step-by-step explanation:

For the first molecule, Al3H, there are:

  • 3 bond pairs and 0 lone pairs on the main atom
  • The total number of electron pairs is 3.
  • So, the hybridization of the molecule will be sp2, and the shape according to VSEPR theory will be a trigonal planar

For the second molecule, CH2F2, there are:

  • 4 bond pairs and 0 lone pair on the central atom. T
  • There are 4 electron pairs
  • Therefore, the hybridization of the molecule will be sp2, and the shape will be tetrahedral

For the third molecule, PH3, there are

  • 3 bond pairs and 1 lone pair.
  • 4 electron pairs.
  • So, the hybridization of the molecule will be sp3. However, the 4th spot on the molecule will be occupied by a lone pair, so the overall shape will be trigonal pyramidal and not tetrahedral

For the final molecule, O3, there are:

  • 2 bond pairs and 1 lone pairs.
  • The number of electron pairs is 3.
  • Hence, the hybridization of the molecule will be sp2. But due to the 3rd position being taken by a lone pair, and the VSEPR theory assuming that electron pairs will sort themselves to decrease the effects of repulsion, the overall shape will be bent and not linear.
