Enantiomers are pairs of molecules that are non-superimposable mirror images of each other. D-arabinose, as shown in the structure, has a specific configuration at each chiral center, and its enantiomer will differ in the configuration of these centers.<\/p>\n\n\n\n<p>Upon analyzing the structures in the image and comparing them to D-arabinose, the enantiomer would be the one that has the opposite configuration at all of the chiral centers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Enantiomer Identification:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>D-arabinose has the following configuration (from top to bottom):\n<ul class=\"wp-block-list\">\n<li>The hydroxyl group on the second carbon (C2) is on the right (as per the Fischer projection).<\/li>\n\n\n\n<li>The hydroxyl group on the third carbon (C3) is on the left.<\/li>\n\n\n\n<li>The hydroxyl group on the fourth carbon (C4) is on the right.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p>For the enantiomer of D-arabinose, the configurations at each of these centers should be reversed, meaning the hydroxyl groups will be flipped at each chiral center.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Name of the Enantiomer:<\/h3>\n\n\n\n<p>The enantiomer of D-arabinose is <strong>L-arabinose<\/strong>, as it is the mirror image of D-arabinose. The L and D notation refers to the configuration of the molecule relative to D- and L-glyceraldehyde, which is the reference compound for these terms. Specifically, L-arabinose has the same configuration at each chiral center as D-arabinose but with opposite stereochemistry.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Correct Answer:<\/h3>\n\n\n\n<p>The enantiomer of D-arabinose is <strong>L-arabinose<\/strong>, and the corresponding structure is the one where the hydroxyl groups are reversed at every chiral center.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1398.jpeg\" alt=\"\" class=\"wp-image-42157\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1398.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1398-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1398-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Consider the structure of D-arabinose.
