Question

The total number of chiral compound/s from the following is ________

Hint:

A chiral center is a carbon atom with four different groups attached to it. Sym metry in a molecule often eliminates chirality.

Answer 1

Correct Answer: 2

To determine the total number of chiral compounds, we must identify which of the given structures have chiral centers.

Step 1: A chiral center is a carbon atom bonded to four different groups.

Compound Analysis:

• - This structure has one chiral center at the carbon bonded to the carboxylic group, phenyl, hydrogen, and the rest of the cyclohexane ring. It is chiral.
• - There is no chiral center as no carbon is bonded to four different groups.
• - The structure has a chiral center on the bridging carbon between the ether linkages, bonded to three differently substituted aromatic rings and one hydrogen. It is chiral.
• - Multiple hydroxyl and carboxyl groups attached to the carbon chain show no chiral centers as symmetrical atoms are observed due to plane symmetry.
• - There is no chiral center observable within this symmetrical structure.

Final Count: There are 2 chiral compounds identified.

This is confirmed to fit within the provided range of (2,2).
