An organic compound with molecular formula `C_6 H_(12)` upon ozonolysis gives only acetone as the product. The compound is :

Options

A. fructose
B. glucose
C. mannose
D. sucrose

Answer

A

Explanation

(a) Since the compound forms a yellow crystalline solid, i.e. osazone with phenylhydrazine, it may be an aldohexose or a ketohexose. Further, since on reduction, compound forms a mixture of sorbitol and mannitol, it must be a ketohexose, i.e. fructose. Recall that glucose on reduction gives only one alcohol glucitol (Sorbitol)
