Which of the carbon atoms present in the molecule given below are asymmetric?
(a) 1,2,3,4 (b) 2,3 (c) 1,4 (d) 1,2,3
Answer: (b). 2 and 3.
Carbon has four valencies. If a carbon atom satisfies all of its four valencies with four different groups then it is termed as asymmetric/chiral carbon. In the given compound, 2 and 3 carbon are bonded to four different groups, so these are asymmetric.
