This is the answer to chapter 22, problem number 45 from the smith organic chemistry textbook.

This problem says, draw the product formed when pentanoil chloride is treated with each reagent.
00:18
And so i've drawn pentanoil chloride at the top of the screen here.
00:22
It's just a five -carbon acid chloride.
00:25
Okay.
00:27
And so these are all going to be substitution -type reactions where whatever is acting as, as our nucleophile is going to replace the chlorine in this chloride, in this acid chloride.
00:40
Okay, so for a, we have water and pyridine, and so that's going to make a carboxylic acid.
00:53
Okay.
00:54
And so we end up with the carboxylic acid here.
00:58
For b, we're using ethanol and pyridine.
01:04
And so instead of a carboxylic acid, we're going to end up with the flaxylic acid.
01:09
Ester.
01:15
Okay.
01:16
For c, we're using a carboxylate ion.
01:21
And so this is going to give us the anhydride...
