  • Analyzing structure A, A appears to have 4 groups attached on the central atom. 
  • So this will have  4 electron groups which are all bonding groups
  • This structure is  tetrahedral which is  AX4 (A is central atom, X is the substituents)

  • B appears to be a T-shaped molecule with 3 groups on it but AXdoesnt follow a T-shape geometry. AX3 follows a trigonal planar geometry.

Problem Details

The following figures show several molecular geometries.Three ball and stick models are depicted. Picture a is tetrahedral shapre with four balls attached to center. Picture b is T shaped with three balls attached to center. Figure C is square pyramidal with five balls attached to center.

Give the number of total electron groups, the number of bonding groups, and the number of lone pairs for (a) geometry.
