Question

Which of the following is true regarding metamerism?

• A. Different relative position around polyvalent functional group
• B. Compounds with different empirical weight
• C. Compounds with different vapor density
• D. Same structural formula

Answer 1

The correct option is A Different relative position around polyvalent functional group

The correct answer is option (a) because isomers in which there is a difference in relative position around polyvalent functional groups is known as metamerism. In metamerism, compounds have different empirical weight, compounds have different vapor density and different structural formula. Example : diethylether, methylpropyl ether.
