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-nitrobenzaldehyde
p-ethylbenzaldehyde
p-chlorobenzaldehyde
p-methoxybenzaldehyde
