propanoic acid does not exhibit optical isomerism why​

Answer 1

Answer:

I will give you the answer tomorrow

Answer 2

propanoic acid does not exhibit optical isomerism because of the absence of chiral carbon

• The formula of propanoic acid is CH₃CH₂COOH.
• It is optically inactive due to the absence of a chiral carbon atom.
• We know carbon has four valencies, if these four valencies are satisfied by four different carbon atoms then it is called chiral carbon.
• But in the case of propanoic acid as you can see there is no carbon (chiral carbon) whose four valencies are satisfied by four different atoms.
• A substance capable of rotating the plane of polarized light passing through it is called an optically active compound.
• Example: sugar solution is optically active.
