Question

How many organic compound(s) is/are correctly matched with number of chiral carbon(s) present in it's structure:
(i) Histamine $=0$

(ii) Chloramphenicol $=2$

(iii) Penicillin $=3$

(iv) Aspartame $=4$

(v) Sucralose $=9$

Answer 1

An asymmetric carbon atom (chiral carbon) is a carbon atom that is attached to four different types of atoms or groups of atoms. The histamine has two chiral centres, each of which is of the $\left(\right.R\left.\right)$ absolute configuration in the Dextrorotatory product.
