Shift End Ctrl Ins 4. Which of the following doesn't have an sp' hybridized atom? a) CHiCOOH b) BH e) NH )NH4 e) None of the above S. Whst is the molecular shape for a central atom that has Sheee bonds and two non-bonding pairs? al square pyramid b) trigonal bipyramid clear di see sa e) none of the above 6 In which of the following anoms is the 2s cebital closest to the nucleus F) S G) Ci H) P l) Si J) They are the same distance in all of these atoms 7. Which of the following does not have a dipole moment? (Electronegative of carbon- 2.5, hydrogen - 2.1 and chlorine-3.0 b) CHCl d) CH CI el None of the above

Explanation / Answer

4. In acetic acid the carboxylic carbon is in SP2 hybridization state. So option A is correct

5. trigonal bypiramid is correct answer. Example is ClF3

6. All of them have same distance to 2s orbital from nucleus.

7. Carbon tetra chloride (CCl4) has zero dipole moment. Since all four Cl atoms attracts sigma bonded electrons towards them, results in zero charge on central C atom.
