Which of the carbon atoms present in the molecule given below are asymmetric?
(i) a, b, c, d
(ii) b, c
(iii) a, d
(iv) a, b, c
(b) Carbon has four valencies. When all those four valencies are attached with four different atoms or groups then the carbon is called asymmetric/ chiral carbon. Here, ‘b’ and ‘c’ are attached to four different atoms/ groups. Hence, these are asymmetric.
