In this molecule, the <strong>NH\u2082<\/strong> group and the <strong>OH<\/strong> group are potential hydrogen bond donors.<\/li>\n\n\n\n<li><strong>H-bond acceptors<\/strong> are atoms that can accept a hydrogen bond, usually due to their lone pairs. The <strong>NH\u2082<\/strong> group (because nitrogen has a lone pair), and the <strong>O<\/strong> atoms in the <strong>CO\u2082H<\/strong> group are potential hydrogen bond acceptors.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">The Parentheses<\/h3>\n\n\n\n<p>The parentheses <strong>(CH\u2083)\u2082<\/strong> around the methyl groups indicate that the two <strong>CH\u2083<\/strong> groups are both attached to the same carbon atom in the isopropyl group. This notation avoids writing the full structure repeatedly and simplifies the chemical representation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1377.jpeg\" alt=\"\" class=\"wp-image-264207\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Draw the complete Lewis structure of (CH3)2CHCH(NH2)CO2H and identify all H-bond donors and all H-bond acceptors.
