Directions for Question: The questions consist of two statements each, printed as assertion and reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: The term tautomerism was introduced by Maxwell in order to explain the chemical reactivity of a substance according to two possible structures Reason: Metamers can also be chain isomers or position isomers.A) If both A and R are true, and R is a correct explanation of the A.
B) If both A and R are true, but R is not a correct explanation of the A.
C) If A is true, but R is false.
D) If both A and R are false.
Correct Answer: C
Solution :
Metamers differ in nature of alkyl groups attached to the same functional group. e.g. \[\underset{Methyl\,propyl\,ether}{\mathop{C{{H}_{3}}-O-{{C}_{3}}{{H}_{7}}}}\,\] \[\underset{Diethyl\,ether}{\mathop{{{C}_{2}}{{H}_{5}}-O-{{C}_{2}}{{H}_{5}}}}\,\]
