Predict the geometry of the following ions. (Type the numbers corresponding to the correct geometry in the boxes next to the formula.)Electron Domain Molecular (a) NH4+ (b) NH2- (c) CO3 2- (d) IC2- 1 bent 2 linear 3 octahedral 4 seesaw-shaped 5 square pyramidal 7 tetrahedral 8 trigonal bipyramidal 9 trigonal planner 10 trigonal pyramidal 11 T-shaped

Answer 1

The geometry of the molecule can be determine by the number of electron groups on the central atom. (a)NH4: Here, the central atom is nitrogen(N).Itis bonded with four hydrogen atoms and the formal charge on nitrogen atom is +1 It contains four bonding groups with zero lone pairs So, the electron geometry is tetrahedral The molecular geometry is tetrahedral. (b) NH2: Here, the central atom is nitrogen(N).Itis bonded with two hydrogen atoms and the formal charge on nitrogen atom is-1. It contains two bonding groups with two lone pairs. So, the electron geometry is tetrahedral The molecular geometry is bent. 2- Here, the central atom is carbon(C). It is bonded with three carbon atoms with the formal charge - 2 It contains three bon ding groups with zero lone pairs. So, the electron geometry is trigonal planar The molecular geometry is trigonal planar. Here, the central atom is iodine[I). It is bonded with two chlorine atoms with the formal charge-1 It contains two bonding groups with three lone pairs. So, the electron geometry is trigonal bipyrami dal The molecular geometry is linear
