Question

The compound which shows metamerism is :

(1) C₅H₁₂

(2) C₃H₈O

(3) C₃H₆O

(4) C₄H₁₀O

Answer 1

Correct option is (4) C₄H₁₀O 

This molecular formula is applicable for homologous series ether (–O–) a bivalent functional group and as we know ether with minimum four-C shows metamerism. CH3–CH2–O–CH2–CH3 & CH3–O–CH2–CH2–CH3 are metamers.
