The rates of thermolysis of a variety of cis- and trans-azoalkanes have been measured over a range of temperatures in order to settle a controversy concerning the mechanism of the reaction. In ethanol an unstable cis- azoalkane decomposed at a rate that was followed by observing the N2 evolution, and this led to the rate constants given in the

A website promoting the use of alternative energy vehicles and hybrid technologies claims that, \"A typical automobile in the USA uses about 1.5 gallons of gasoline every day, producing about 25 lbs of carbon dioxide.\" To determine the truth of this statement, calculate how many pounds of carbon dioxide are produced when 1.500 gallons of gasoline

Enol and keto functional groups interconvert readily in acidic and basic solution. This reversible reaction is called a tautomerization. Complete the acidcatalyzed mechanism for the conversion of dimethyl ketone to its enol form by drawing in the missing curved arrows. . , H. Both lone pairs remain on the oxygen. Where is there another pair
