A) chain isomers
B) keto-enol tautomers
C) geometrical isomers
D) position isomers
Correct Answer: B
Solution :
Isomers differ in the arangement of atoms but exist in dynamic equilibrium with each other shows the tautomerism. Acetaldehyde and vinyl alcohol are keto-enol tautomers. \[\underset{\begin{smallmatrix} acetaldehyde \\ \,\,(keto\text{ }form) \end{smallmatrix}}{\mathop{C{{H}_{3}}-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-H}}\,\underset{\begin{smallmatrix} vinyl\text{ }alcohol \\ \,(enol\text{ }form) \end{smallmatrix}}{\mathop{C{{H}_{2}}=\overset{\begin{smallmatrix} OH \\ || \end{smallmatrix}}{\mathop{C}}\,-H}}\,\]You need to login to perform this action.
