"Sawbuck" is also a slang term for a U.S. $10 bill, derived from the similarity between the shape of a sawbuck device
A value of ethyl cyclohexane, the A value is reduced from what would be predicted based purely on enthalpic terms. Due to these favorable entropic conditions, the steric relevance of an ethyl group is similar to that of a methyl substituent. The following table lists some common A-values in kcal/mol: These values have been measured at different institutes under different conditions. One of the original experiments performed by Winston and Holness was measuring the rate of oxidation in trans and cis substituted rings using a Chromium catalyst. The large tBu group used locks the conformation of each molecule placing it equatorial (cis
