Hello everyone. Today, we have the following problem. What is the name and condensed structure of the compound produced by the condensation reaction of benzo acid with one propanol. So when we have these two re reagents combined, this is known as a Fisher ester application fisher verification. So if we draw out our Ben Zoic acid, which is essentially a carboxylic acid bound to a benzene ring as the following azotic acid, which is being reactive with one propanol, which is the following. This will combine to create an ester via condensation. So what will essentially happen is that the hydrogen on this benzo acid will be replaced by the alkyl group that's attached to our alcohol such that we form the following. So we have our product here, which is actually going to be named using first the akil chain as a substituent, which was a Propol group. And then we will name the parent chain, which is derived from the carboxylic acid portion of the ether in which we will remove the e and replace it with a weight. So instead of the benzene, this will just be Ben Zoe. And in addition to this prophyl benzoate we will form water as a by-product. And so with that, we have solved the problem overall, I hope it helped. And until next time.
