Which among the following compounds will have meso form

Question

Which among the following compounds will have meso form (A) CH2OH - CHOH - CHOH - CHO (B) CH2OH - CHOH - CHOH - COOH (C) CH2OH - (CHOH)2 - CH2OH (D) C6H3 - CHCl - CHOH - CH3

CH2OH⎯ CHOH⎯ CHOH⎯ COOH will have meso form. The structures that have plane of symmetry, which can divide it into two equal and identical halves are called meso structures. In the given compounds, only structure (b) has plane of symmetry, hence it is a meso compound.

Q. Which among the following compounds will have meso form

$C H_{2} O H - C H O H - C H O H - C H O$

$C H_{2} O H - C H O H - C H O H - COO H$

$C H_{2} O H - (C H O H)_{2} - C H_{2} O H$

$C_{6} H_{3} - C H Cl - C H O H - C H_{3}$

$C H_{2} O H ⎯ C H O H ⎯ C H O H ⎯ COO H$

will have meso form.
