Question

Which of the carbon atoms present in the molecule given below are asymmetric?

• A. (i), (ii), (iii), (iv)
• B. (ii), (iii)
• C. (i), (iv)
• D. (i), (ii), (iii)

Answer 1

The correct option is B (ii), (iii)

Asymmetric carbon is the chiral carbon which is $s{p}^3$ hybridised carbon attach to four different substituents.

Since (ii) &(iii) are $s{p}^3$ hybridised also four different substituents are attached to them so they are chiral.

$\stackrel{\left(i\right)}{C}OOH-\underset{H}{\underset{|}{\stackrel{OH}{\stackrel{\left(ii\right)|}{C}}}}-\underset{OH}{\underset{|}{\stackrel{H}{\stackrel{\left(iii\right)|}{C}}}}-\stackrel{\left(iv\right)}{COOH}$
