what accounts for the large amount of ring strain in cyclopropane and cyclobutane? (Hint: what bond angle does an sp^y hybridized carbon prefer? What angles are necessary for each of the geometric shapes you are building?)
The insecticide DDT has a half-life in the human body of about 7 years. That is, in 7 years its concentration.( Although DDT is no longer in use in the United States).

Dibenzalacetone has two carbon-carbon double bonds. How many geometric isomers are possible? Draw all possible geometric isomers of the product and look up their melting points.
A particular reactant decomposes with a half-life of 171 s when its initial concentration is 0.329 M. The same reactant decomposes with a half-life of 245 s when its initial concentration is 0.230 M. determine the reaction order. calculate the rat..
Aqueous solutions of each of the following salts {sodium acetate, sodium phosphate, sodium formate, and sodium carbonate} have a pH that is > 7. The reason for this is that the anion undergoes a so-called "hydrolysis reaction".
