Which of the following bonds is a nonpolar covalent bond?
1) H – F
2) N – F
3) F – CI
4) F -F<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is:<\/p>\n\n\n\n 4) F – F<\/strong><\/p>\n\n\n\n A nonpolar covalent bond<\/strong> occurs when two atoms share electrons equally because they have the same electronegativity, meaning they have an identical ability to attract and hold onto electrons. In such a bond, the electron density is evenly distributed between the two atoms, resulting in no permanent dipole moment.<\/p>\n\n\n\n To understand why F – F is a nonpolar covalent bond, let’s break down the options:<\/p>\n\n\n\n 1) H – F<\/strong>: The electronegativity of fluorine (F)<\/strong> is 3.98, while that of hydrogen (H)<\/strong> is 2.20. The difference in electronegativity (3.98 – 2.20 = 1.78) is significant. This creates a polar covalent bond<\/strong>, where fluorine attracts the shared electrons more strongly than hydrogen, resulting in a dipole moment with fluorine having a partial negative charge and hydrogen a partial positive charge.<\/p>\n\n\n\n 2) N – F<\/strong>: Nitrogen (N) has an electronegativity of 3.04, and fluorine (F) has an electronegativity of 3.98. The electronegativity difference here is 0.94, which is also large enough to create a polar covalent bond<\/strong>, where fluorine attracts the shared electrons more strongly than nitrogen.<\/p>\n\n\n\n 3) F – Cl<\/strong>: Fluorine (F) has an electronegativity of 3.98, and chlorine (Cl) has an electronegativity of 3.16. The electronegativity difference is 0.82, which is moderate enough to cause a polar covalent bond<\/strong>. Fluorine pulls the electron pair slightly more than chlorine, creating a dipole moment.<\/p>\n\n\n\n 4) F – F<\/strong>: Fluorine atoms are identical and have the same electronegativity of 3.98. Since both atoms equally share the electrons, there is no difference in electron distribution, making this a nonpolar covalent bond<\/strong>. There is no dipole, and the electrons are shared equally.<\/p>\n\n\n\n Thus, the F – F<\/strong> bond is the only nonpolar covalent bond in the options provided.<\/p>\n","protected":false},"excerpt":{"rendered":" Which of the following bonds is a nonpolar covalent bond?1) H – F2) N – F3) F – CI4) F -F The Correct Answer and Explanation is: The correct answer is: 4) F – F Explanation: A nonpolar covalent bond occurs when two atoms share electrons equally because they have the same electronegativity, meaning they […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[25],"tags":[],"class_list":["post-162106","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/162106","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=162106"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/162106\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=162106"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=162106"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=162106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Explanation:<\/h3>\n\n\n\n
