When looking at the Sn2 reaction between diastereomers of 4-tert-butyl-1-chlorocyclohexane and KOH in acetronile, it is observed that the cis derivative reacts 1,000 times faster than the trans derivatie. Rationalize this phenomenom based on what you know regarding cyclohexane derivatives and Sn2 reactions.
Calculate the amount of energy needed in calories to heat 145 g of water from 22.3 degrees celsius to 75.0 degrees celsius. (water in j/g degree celsius = 4.184, cal/ g degree celsius = 1)
