These compounds are known as <strong>hydrogen halides<\/strong> or more broadly as <strong>hydrides of nonmetals<\/strong>. When these compounds dissolve in water, they often produce acids.<\/p>\n\n\n\n<p>For example, when hydrogen bonds with chlorine (a nonmetal), it forms <strong>hydrogen chloride (HCl)<\/strong>. When HCl is dissolved in water, it forms <strong>hydrochloric acid<\/strong>, a strong acid: HCl&nbsp;(g)\u2192HCl&nbsp;(aq)\u2192H++Cl\u2212\\text{HCl (g)} \\rightarrow \\text{HCl (aq)} \\rightarrow \\text{H}^+ + \\text{Cl}^-<\/p>\n\n\n\n<p>The key reason nonmetals form acidic hydrogen compounds is due to their <strong>high electronegativity<\/strong>. Electronegativity is the tendency of an atom to attract electrons. Nonmetals, especially those in groups 15, 16, and 17 (such as nitrogen, oxygen, sulfur, and the halogens), have high electronegativities and tend to <strong>pull the shared electrons in the H\u2013X bond toward themselves<\/strong>. This makes the hydrogen atom more positive and easily released as a proton (<strong>H\u207a<\/strong>) in solution, which is the defining characteristic of acids.<\/p>\n\n\n\n<p>Here are a few examples of acidic hydrogen compounds formed with nonmetals:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>HF (hydrogen fluoride)<\/strong> \u2192 hydrofluoric acid<\/li>\n\n\n\n<li><strong>H\u2082S (hydrogen sulfide)<\/strong> \u2192 hydrosulfuric acid<\/li>\n\n\n\n<li><strong>HNO\u2083 (nitric acid)<\/strong> \u2192 derived from nitrogen<\/li>\n\n\n\n<li><strong>H\u2082SO\u2084 (sulfuric acid)<\/strong> \u2192 derived from sulfur<\/li>\n<\/ul>\n\n\n\n<p>In contrast, <strong>metals<\/strong> typically form <strong>basic<\/strong> or <strong>neutral hydrides<\/strong> (like sodium hydride, NaH) and do not release H\u207a ions in water.<\/p>\n\n\n\n<p>Therefore, <strong>nonmetals<\/strong> are the correct answer because they form hydrogen compounds that can release protons in aqueous solution, exhibiting acidic behavior.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner4-103.jpeg\" alt=\"\" class=\"wp-image-223620\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The what form acidic compounds with hydrogen The Correct Answer and Explanation is: Correct Answer: Nonmetals form acidic compounds with hydrogen.
