Question

which alcohol and carboxylic acid would produce benzyl isobutyrate by Fischer esterification? and which alcohol and carboxylic acid would produce isobutyl benzoate by fischer esterification?

Since this is not my area of expertise, I searched Google under the key words "<I>Fischer esterification</I>" to get these possible sources:

You can continue the search using other terms as key words.

I hope this helps. Thanks for asking.
