(a)
Interpretation:
Whether a balloon filled with the given gas would rise in the air or drop to the ground is to be stated.
Concept introduction:
Density is the ratio of mass to its volume. For solid bodies densities are usually expressed in the units of grams per cubic centimeter, for liquids in the units of grams per milliliter and for gases in units of grams per liter.

- Synthesis of Ibuprofen-Part 1: 1. What characteristic absorption band changes would you expect in the IR spectrum on going from p-isobutylacetophenone to 1-(4-isobutylphenyl)-ethanol and then to 1-(4-isobutylphenyl)-1-choroethane as you did in the experiment today? Give approximate wavenumbers associated with each functional group change.
