|---|---|---|
(I)
| (A) Metamers | (P) Structural isomers |
(II)
| (B) Tautomer | (Q) Stereoisomers |
(III)
| (C) Geometrical isomer | (R) Non identical |
(IV)
| (D) Functional isomers | (S) Constitutional isomers |
.
Choose correct option among the following?
Options:
Answer:
Solution:
Structure Analysis: The first structure is an amide (CH₃CONH₂) and the second structure is its imidic acid form (CH₃C(OH)=NH).
Relationship: These two structures differ only in the position of a proton (hydrogen atom) and a double bond, which makes them tautomers (matches B).
Classification: Tautomerism is a special functional dynamic type of structural isomerism (matches P) and is also classified under constitutional isomers (matches S).
Final Match: Therefore, the combination (II), (B), (P) is completely correct and matches option (B).
