The strength of a Br\u00f8nsted acid depends on how easily it can donate this proton. This is largely determined by the <strong>stability of its conjugate base<\/strong>\u2014the more stable the conjugate base, the stronger the acid.<\/p>\n\n\n\n<p>The conjugate base of a carboxylic acid is a <strong>carboxylate ion (RCOO\u207b)<\/strong>. When a proton is removed from the \u2013COOH group, the remaining negative charge can be stabilized by electron-withdrawing groups through a process called <strong>inductive effect<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Inductive Effect:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Electron-withdrawing groups, like halogens, pull electron density through the sigma bonds, stabilizing the negative charge on the conjugate base.<\/li>\n\n\n\n<li>The <strong>stronger the electron-withdrawing group<\/strong>, the greater the acid strength.<\/li>\n\n\n\n<li><strong>Fluorine<\/strong> is more electronegative than <strong>bromine<\/strong>, meaning it pulls electron density more effectively.<\/li>\n\n\n\n<li>Even though both halogens are two carbons away, <strong>fluorine\u2019s effect is stronger<\/strong> than bromine\u2019s.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, <strong>CH\u2082FCH\u2082COOH<\/strong> has a <strong>more stabilized conjugate base<\/strong> due to the stronger inductive effect of fluorine, making it a <strong>stronger Br\u00f8nsted acid<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Summary:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fluorine is more electronegative than bromine.<\/li>\n\n\n\n<li>Fluorine stabilizes the conjugate base better.<\/li>\n\n\n\n<li>CH\u2082FCH\u2082COOH donates H\u207a more easily.<\/li>\n<\/ul>\n\n\n\n<p><strong>Thus, CH\u2082FCH\u2082COOH is the stronger Br\u00f8nsted acid<\/strong><\/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-banner5-694.jpeg\" alt=\"\" class=\"wp-image-238147\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Q 3.97: Which of the following compounds is the strongest Bronsted acid?
