When the following aldohexose exists in its D-configuration, the total number of stereoisomers in its pyranose form is :
$\mathrm{CHO}-\mathrm{CH}_{2}-\mathrm{CHOH}-\mathrm{CHOH}-\mathrm{CHOH}-\mathrm{CH}_{2} \mathrm{OH}$
Solution
Thus, total number of stereoisomers in pyranose form of D-configuration $=2^{3}=8$
