Vedclass · Answer

(A) An aldopentose has the structure $CHO-(CHOH)_3-CH_2OH$. Periodic acid $(HIO_4)$ cleaves vicinal diols and $\alpha$-hydroxy carbonyl compounds. For an aldopentose,the reaction proceeds as follows: $CHO-(CHOH)_3-CH_2OH + 4HIO_4 	o 4HCO_2H + HCHO$. Thus,the products obtained are $4$ moles of formic acid $(HCO_2H)$ and $1$ mole of formaldehyde $(HCHO)$.
