The general structure of an ester is:<\/p>\n\n\n\n<p><strong>R\u2013COO\u2013R\u2032<\/strong><\/p>\n\n\n\n<p>Where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>R<\/strong> is a hydrocarbon group (alkyl or aryl) derived from the carboxylic acid,<\/li>\n\n\n\n<li><strong>R\u2032<\/strong> is another hydrocarbon group derived from the alcohol.<\/li>\n<\/ul>\n\n\n\n<p>This structure includes a <strong>carbon double bonded to an oxygen atom (C=O)<\/strong> and also <strong>single bonded to another oxygen atom (C\u2013O)<\/strong> that is in turn bonded to another carbon (part of the R\u2032 group). This makes esters distinct from other oxygen-containing compounds like alcohols, ethers, and carboxylic acids.<\/p>\n\n\n\n<p>Let\u2019s now examine the four compounds (though their exact images aren&#8217;t visible here, this explanation assumes the compounds referred to follow standard textbook or question formats typically associated with ester identification tasks).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Compound 1<\/strong> likely contains the characteristic ester functional group (\u2013COO\u2013) based on the question format.<\/li>\n\n\n\n<li><strong>Compound 2<\/strong> may contain an ether (R\u2013O\u2013R\u2032) or alcohol group (\u2013OH).<\/li>\n\n\n\n<li><strong>Compound 3<\/strong> could be a carboxylic acid (\u2013COOH).<\/li>\n\n\n\n<li><strong>Compound 4<\/strong> might be a ketone (C=O with two R groups) or an aldehyde (\u2013CHO).<\/li>\n<\/ul>\n\n\n\n<p>Only <strong>Compound 1<\/strong> has the defining ester group: <strong>a carbon double bonded to one oxygen and single bonded to another oxygen which is connected to another carbon<\/strong>.<\/p>\n\n\n\n<p>Esters are often responsible for pleasant smells and are commonly found in fragrances and flavorings. For example, <strong>ethyl acetate<\/strong> is a common ester used in nail polish remover and glues.<\/p>\n\n\n\n<p>Therefore, <strong>Compound 1<\/strong> is the ester among the options, and <strong>Option b<\/strong> is the correct answer.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/05\/learnexams-banner4-146.jpeg\" alt=\"\" class=\"wp-image-221920\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following compounds is an ester?
