Among all single bonds, only those involving hydrogen have signals in the functional group region of an infrared spectrum. What is the main reason behind this phenomenon?
a.) All X-H bonds (X=any element) are much stronger than any other single bond.
b.) Hydrogen has a much smaller atomic mass.
c.) All X-H bonds (X=any element) are much shorter than any other single bond.
d.) All X-H bonds (X=any element) are more polar than any other single bond.
The rate constant of some reactions double with every 10 degree rise in temperature. Assume that a reaction takes place at 295 K and 305 K. What must the activation energy be for the rate constant to double as described?
The reaction that you will conduct in this experiment is known as a "haloform" reaction. When a methyl ketone is used as a substrate, what is it converted to in this reaction?
how you will prepare 3-methly-1-butanol from a grignard reagent and any needed aldehyde or ketone.
