Predict whether the following compounds will undergo the benzoin condensation, faster slower than benzaldehyde or give no reaction. You must think about the intermediate and the nucleophile. There are several factors to consider, first what will promote getting to the intermediate and then what will promote getting to the product.
p-nitrobenzaldehydep-ethylbenzaldehydep-chlorobenzaldehydep-methoxybenzaldehyde
Find the temp (in K) above which a reaction with a delta H of 123.0 kj/mol and a delta S of 90.0 J/k*mol becomes spontaneous.
How much energy is needed to warm 0.500 g of silver from 25.0 degree C to 27.5 degree C? The specific heat of silver is 0.24J /g. degree C
Calculate the number of grams of NaOH per 100ml to give a pH8.0 solution if pure water at pH7.0 is used in the experiment. Repeat this calculation for a pH6.0 solution using HCl.
