Q. Which of the following compounds will show metamerism?
A) $CH_{3} - \ CO - C_{2}H_{5}$
B) $C_{2}H_{5} - S - C_{2}H_{5}$
C) $CH_{3} - O - CH_{3}$
D) $CH_{3} - O - C_{2}H_{5}$
Explanation
(b)
Compounds having bivalent functional group (like C=O, –O–, –S – etc) with atleast 4 carbon atoms (in case of ether and thioether) or atleast 5 carbon atoms (in case of ketones) exhibit metamerism. Hence, $C_{2}H_{5} - S - C_{2}H_{5}$ will show metamerism.
