Question

16. () (8 pts) Draw the other molecule needed to make the product in 161, HO assuming you have a chloride.

Answer 1

As in the question, it is given that we have one chloride. there are many ways by which chlorides can be converted into acid.

1. Treatment of acid chlorides with water leads to the formation of carboxylic acids. This is called hydrolysis of acid chlorides.

i.e by adding one water (H2O) molecule , we can carry out this conversion.

and H2O + HCI OH CS Adidneblonidenscanner Carboxylic acid

Below is the proposed mechanism for the same reaction:

2. we can also get the desired product by the reaction of the Grignard reagent with formyl chloride:

H oxidation u oridating ou per con Thus, by taking 2- Cyclo Pentyl reguard heagent also acetic acid We can get desired froduct. CScanned with CamScanner

The reagent used to carry out the direct conversion of aldehyde to carboxylic acid is CrO3 /acetone at 0oC.

hope your query is solved!
