MCQ
Methyl $- \alpha - D-$ glucoside and methyl $- \beta -D-$ glucoside are
  • A
    Epimers
  • ✓
    Anomers
  • C
    Enantiomers
  • D
    Conformational diastereomers
✓

Answer

Correct option: B.
Anomers
b
In $\alpha -D$ glucoside $-OCH_3$ group at $C_1$ is towards right while in $\beta -D$ glucose, it is towards left at $C_1$. Such pairs which differ around only $C_1$ in configuration are called anomers.
