CONCEPT QUESTIONS Mechanism. While the reaction carried out in lab used potassium hydroxide as the catalyst, many other catalysts have been developed to increase regioselectivity and stereoselectivity in aldol condensations. One small molecule catalyst commonly used is proline, a naturally occurring amino acid. The mechanism involves the initial formation of an enamine; predict the structure of this enamine intermediate intermediate...

Given that the initial rate constant is 0.0160s-1 at
an initial temperature of 24 deg C, what would the rate constant be
at a temperature of 100 deg C for the same reaction described in
Part A?
From Part A:
The activation energy of a certain reaction is 31.5 kJ/mol. At
24∘C, the rate constant is 0.0160s−1. T2 = 41C...

Can
you check my answers please?
To answer the questions below use the following information: Cyanohydrins are important intermediates in the synthesis of c-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is...
