Q. Which of the following is the first member of monosaccharides?
A) $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ O\ \$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \parallel$
CH_{2}OH —C— CH_{2}OH
B) CH_{2}OH—CHOH —CHO
C) CH_{2}OH —CHOH— CHOH— CHO
D) $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ O\ \$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \parallel$
CH_{2}OH —CHOH —C —CH_{2}OH
Explanation
(b)
Glyceraldehyde $\left( {CH}_{2}OH - CHOH - CHO \right)$ is the first member of monosaccharide.
