In which of the following molecules carbon atom marked with asterik (*) is asymmetric ?

A

(i),(ii),(iii) and (iv)

B

(i), (ii) and (iii)

C

(ii), (iii) and (iv)

D

(i), (iii) and (iv)

Text Solution

Verified by Experts

The correct Answer is:
B
Asymmetric/chiral carbon atom is that in which all of its four valencies with four different groups or atoms. In compound (iv), carbon satisfies two of its valencies with two hydrogen atoms i.e., similar atom.
So, it is not an asymmetric carbon atom while rest of the three molecules have asymmetric carbon as each carbon has satisfied all four valencies with four different groups or atoms.
So, the correct option is (b).
