Multiple choice

Which of the following conversions does not involve change in hybridization but only geometry is changed?

  1. NH3 → NH4+

    2. AlCl3 → AlCl4-

    3. H2O → H3O+

  1. Only 1

  2. 1 and 3

  3. Only 2

  4. 2 and 3

  5. All of the above

B Correct answer
Explanation

In both the cases, only geometry changes. NH3 → NH4+NH3: sp3 hybridization, trigonal pyramidal geometry NH4+: sp3 hybridization, tetrahedral geometry  H2O → H3O+H2O: sp3 hybridization, bent (V-shaped) geometryH3O+: sp3 hybridization, trigonal pyramidal geometry.
