Q. $Meso$-tartaric acid is optically inactive due to the presence of
A) Molecular symmetry
B) Molecular asymmetry
C) External compensation
D) Two asymmetric C-atoms
Explanation
(a)
COOH
|
$H - C - OH$
| plane of symmetry
$H - C - OH$
|
COOH
$Meso$ tartaric acid is optically inactive due to the presence of molecular symmetry. It I optically inactive due to internal compensation, $ie$, the effect of one half of the molecule is neutralized by other
