Question

Glucose forms many derivatives- The derivative which will help to prove the furanose structure is (A) osazone (B) benzoyl (C) acetyl (D) isopropylidene

Tardigrade Admin · Accepted Answer

Formation of isopropylidene derivative requires the presence of two adjacent free -OH groups in cis-orientation which is present only in the furanose form and hence, isopropylidene formation proves the presence of furanose form.
