The correct structure of D(+) Glucose is:

Options:

Correct Answer:

Explanation:

The correct answer is Option (1) → 

Reason:
In D(+)-glucose, the Fischer projection has:

  • CHO at the top and CH₂OH at the bottom

  • The –OH group on the penultimate carbon (C-5) is on the right, which defines the D-configuration

  • The correct sequence of –OH groups from C-2 to C-5 is:
    Right – Left – Right – Right

Only Option 1 shows this correct arrangement, so it represents D(+)-glucose
