Some Basic Principles Of Organic Chemistry Question 299
Question: Meso-tartaric acid is optically inactive due to the presence of [AIIMS 1982; MP PMT 1987]
Options:
A) Molecular symmetry
B) Molecular asymmetry
C) External compensation
D) Two asymmetric C-atoms
Show Answer
Answer:
Correct Answer: A
Solution:
Molecular symmetry Plane of Symmetry Mesotartaric acid is optically inactive due to internal compensation i.e.
the effect one half of the molecule is neutralized by other.
