"WebbHow many alkanes of molecular weight M are chiral? As a particular case let us consider M=100.The general formula for such a alkane is C n H 2 n + 2 where n is the number of carbon atoms. Putting in values of molecular weight we get 12 n + 2 n + 2 = 100 which gives n = 7. So there are 7 carbon atoms. " - Smallest chiral alkane
