The naming convention for binary acids is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Start with the prefix <strong>\u201chydro\u2013\u201d<\/strong><\/li>\n\n\n\n<li>Follow it with the <strong>root<\/strong> of the nonmetal\u2019s name (in this case, <strong>fluor<\/strong> from fluorine)<\/li>\n\n\n\n<li>Add the suffix <strong>\u201c\u2013ic acid\u201d<\/strong><\/li>\n<\/ul>\n\n\n\n<p>So, <strong>HF (aq)<\/strong> becomes:<\/p>\n\n\n\n<p><strong>hydro<\/strong> + <strong>fluor<\/strong> + <strong>ic acid<\/strong> \u2192 <strong>hydrofluoric acid<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Why Other Options Are Incorrect:<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Monohydrogen fluoride<\/strong><br>This name is not used in acid naming.

The &#8220;hydro\u2013&#8221; prefix is missing and it&#8217;s not consistent with IUPAC naming for binary acids.<\/li>\n\n\n\n<li><strong>Hydrogen fluoride<\/strong><br>This is the correct name for <strong>HF in gas form<\/strong>, but not for the aqueous acid.
