Pick out the correct statements: (i) if a compound has no asymmetric carbon atom, it is always achiral. (ii) if a compound has just one asymmetric carbon atom, it is chiral. (iii) if a compound has more than one asymmetric carbon atoms, it may or may not be chiral.

A(i), (ii) and (iii) are correct
B(i) and (ii) only are correct
C(i) and (ii) only are correct
Correct Answer
DOnly (ii) is correct

Solution

(ii) and (iii) only are correct. (i) is not correct as $$\text{Some compounds do not have asymmetric carbon atoms but are still}$$\text{ chiral.Helices, like screws, are chiral because they can exist in left- or right-handed forms.}$$
