Question

Which of the compounds (A-D) depicted above is not a hemiacetal linkage?

• A. Compound A
• B. Compound B
• C. Compound C
• D. Compound D
• E. None of the above (they are all hemiacetals)

Answer 1

The correct option is E None of the above (they are all hemiacetals)

The alcohol and ether attached to the same carbon is known as hemiacetal linkage. In all compounds given, an alcohol is attached to ether. Hence, all the compounds have hemiacetal linkage.

Therefore, $\left(E\right)$ is the correct answer.
