Solution:

Open-chain glucose, $HOCH_{2}\overset{*}{C H O H}\overset{*}{C H O H}\overset{*}{C H O H}\overset{*}{C H O H}CHO$ has, four chiral carbons (asterisked carbons) and open-chain fructose, $HOCH_{2}\overset{*}{C H O H}\overset{*}{C H O H}\overset{*}{C H O H}COCH_{2}OH$ has three chiral carbons.
