Multiple Choice

Draw the following aldotetrose in the proper Fischer projection.

The figure illustrates a Fischer projection. The Fischer projection consists of a vertical line with C H O above and C H 2 O H below. The projection contains two C atoms placed one below the other on the vertical line. The C atoms are numbered from top to bottom. C 2 has a horizontal line drawn across it with H on the left and O H on the right. C 3 has a horizontal line drawn across it with O H on the left and H on the right.

Verified step by step guidance

Identify the structure of the aldotetrose from the first image. It is a four-carbon sugar with an aldehyde group at the top and hydroxyl groups on the second and third carbons.

Recognize that the Fischer projection is a two-dimensional representation of a molecule where the carbon chain is vertical, and horizontal lines represent bonds coming out of the plane towards the viewer.

Determine the configuration of the chiral centers in the given structure. The first chiral center (C2) has the hydroxyl group on the right, and the second chiral center (C3) has the hydroxyl group on the left.

Match the configuration of the chiral centers to one of the Fischer projections provided in the images. The correct Fischer projection will have the same arrangement of hydroxyl groups as the original structure.

Verify that the chosen Fischer projection accurately represents the stereochemistry of the original aldotetrose structure, ensuring that the orientation of each hydroxyl group matches the original structure.
