No product is expected from this reaction.

  1. HI(aq) + NaOH(aq)
  2. H2O(l) + HOCl(aq)
  3. K(s) + H2O (aq)
  4. Xe(g) + H2O(g)
  5. Zn(s) + CuSO4(aq)

Answer(s): D

Explanation:

Noble gases, i.e. Xe, do no react.



What is the geometry of CHCl3?

  1. Linear
  2. Tetrahedral
  3. Octahedral
  4. Trigonal-pyramidal
  5. Trigonal-bipyramidal

Answer(s): B

Explanation:

In CHCl3 there are four ligands and no unpaired electrons, thus CHCl3 is tethahedral.



What is the geometry of CO2?

  1. Linear
  2. Tetrahedral
  3. Octahedral
  4. Trigonal-pyramidal
  5. Trigonal-bipyramidal

Answer(s): A

Explanation:

Carbon forms a double bond with each oxygen atom so there are no unpaired electrons.



What is the geometry of PF5?

  1. Linear
  2. Tetrahedral
  3. Octahedral
  4. Trigonal-pyramidal
  5. Trigonal-bipyramidal

Answer(s): E

Explanation:

There are five ligands that want to maximize the space between them, forming a trigonal-bipyramidal geometry.
