This polarity allows the molecules of acetic acid to form hydrogen bonds with each other. Hydrogen bonds are strong intermolecular forces that hold molecules together. The stronger the intermolecular forces, the higher the boiling point of the substance.<\/p>\n<p>Chloroform, ethanol, and methane are all nonpolar molecules. Nonpolar molecules do not have a positive end or a negative end, so they cannot form hydrogen bonds. The lack of hydrogen bonds in these molecules results in lower boiling points.<\/p>\n<p>Acetic acid has a boiling point of 118 degrees Celsius. Chloroform has a boiling point of 61 degrees Celsius. Ethanol has a boiling point of 78 degrees Celsius. Methane has a boiling point of -161 degrees Celsius.<\/p>\n<p>Therefore, acetic acid has the highest boiling point of the four substances.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;acetic acid&#8221; option2=&#8221;chloroform&#8221; option3=&#8221;ethanol&#8221; option4=&#8221;methane&#8221; correct=&#8221;option1&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[637],"tags":[],"class_list":["post-5420","post","type-post","status-publish","format-standard","hentry","category-organic-chemistry","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Which of the following mixtures of carbon has the highest boiling point?
