What observed rotation is expected when a 1.50 M solution of (R)-2-butanol is mixed with an equal volume of a 0.750 M solution of racemic 2-butanol, and the resulting solution is analyzed in a sample container that is 1 dm long? The specific rotation of (R)-2-butanol is -13.9 degrees mL g-1 dm-1.deg
Does that indicate the original alcohol is in that mixture? What is the source of 2-bromopentane?
A zero-order reaction has a constant rate of 3.50×10-4 M/rm s. If after 65.0 seconds the concentration has dropped to 1.00×10-2 M, what was the initial concentration?
