Question

Which of the following are chiral (optically active)?

• A. Benzoic acid
• B. Pent-2,3-diene $(C{H}_3-CH=C=CH-C{H}_3)$
• C. Hex-2,3,4-triene $(C{H}_3-CH=C=C=CH-C{H}_3)$
• D. 1,1,3,3- tetrachloroprop-1,2-diene $(CC{I}_2=C=C{I}_2)$
• E. 2-(2-Carboxy-6-Nitrobenzyl)-3- Nitrobenzoicacid

Answer 1

The correct option is A Benzoic acid

: Asymmetric $C$

$\therefore$ Chirating is present

$\therefore$ Symmetric $C$

$\therefore$ Chirality Absent

$\therefore$ Symmetricity present

$\therefore$ Chirality Absent

$\therefore$ Symmetricity present

$\therefore$ Chirality Absent
