To understand this in more detail, let&#8217;s break down the question in the context of nucleophilicity and basicity.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Nucleophile<\/strong>: A nucleophile is a species that donates electrons to an electrophile to form a new bond. The strength of a nucleophile depends on its electron density, charge, and polarizability. A strong nucleophile is typically negatively charged and has a high electron density.<\/li>\n\n\n\n<li><strong>Base<\/strong>: A base is a species that accepts a proton (H+). The strength of a base is measured by its ability to accept a proton, which is related to the stability of its conjugate acid.<\/li>\n<\/ul>\n\n\n\n<p><strong>NaOH (Sodium Hydroxide)<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sodium hydroxide dissociates in water to form Na+ (a spectator ion) and OH\u2013 (hydroxide ion).<\/li>\n\n\n\n<li><strong>Hydroxide (OH\u2013)<\/strong> is a strong base because it can readily accept a proton to form water (H2O), and water is a very weak acid. It is commonly used in reactions involving deprotonation, like in acid-base reactions.<\/li>\n\n\n\n<li>However, hydroxide (OH\u2013) is also a <strong>strong nucleophile<\/strong> because it is negatively charged and has a high electron density, making it highly reactive in nucleophilic substitution reactions, especially in an SN2 mechanism.<\/li>\n<\/ul>\n\n\n\n<p>In an <strong>SN2 reaction<\/strong>, the nucleophile attacks the electrophile (typically a carbon bonded to a leaving group) from the opposite side, resulting in a backside attack and inversion of configuration. The strong nucleophilicity of OH\u2013 helps drive this process forward, making it effective in SN2 reactions.<\/p>\n\n\n\n<p>Thus, NaOH is a <strong>strong nucleophile<\/strong> and contributes to the success of the SN2 mechanism, despite also being a strong base. Its dual character allows it to perform effectively in both types of reactions, but in this context, its nucleophilicity is most relevant.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Is NaOH a strong base or nucleophile in an SN2 reaction?A) Strong baseB) Weak baseC) Strong nucleophileD) Weak nucleophile The Correct Answer and Explanation is : The correct answer is: C) Strong nucleophile Explanation: NaOH (sodium hydroxide) is considered a strong nucleophile in SN2 reactions due to its ability to donate electrons quickly to form [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","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-162352","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/162352","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=162352"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/162352\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=162352"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=162352"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=162352"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
