Q10 / 69 · JEE Advanced 2008 (Paper 1) · Chemistry

$$ \text { The correct statement(s) concerning the structures } E, F \text { and } G \text { is are } $$ Figure

  • A
    $E, F$ and $G$ are resonance structures
  • Correct answer
    B
    $E, F$ and $E, G$ are tautomers
  • Correct answer
    C
    $F$ and $G$ are geometrical isomers
  • Correct answer
    D
    $F$ and $G$ are diastereomers

Solution

$E$ and $F$ possess different place of atoms, in addition to electron pair, can be isomers only and not the resonance structures. Geometrical isomers are stereoisomers but not enantiomers called diastereomers

Hence, the correct answer is options: 'B', 'C', 'D'.
