The tetrahedral shape is characterized by four bonded atoms surrounding a central atom, forming bond angles of 109.5 degrees<\/strong>. This arrangement results from the repulsion between electron pairs in a three-dimensional structure.<\/p>\n\n\n\n A tetrahedral shape cannot<\/strong> have bond angles of 120 degrees or 90 degrees<\/strong> because such angles are characteristic of other molecular geometries. Trigonal planar geometry<\/strong> exhibits bond angles of 120 degrees<\/strong>, typically occurring when three atoms are arranged symmetrically around a central atom. Octahedral geometry<\/strong>, on the other hand, features 90-degree angles<\/strong> due to its six bonded atoms positioned at equal distances around the central atom.<\/p>\n\n\n\n Pyramidal geometry<\/strong>, such as trigonal pyramidal, results from the presence of one lone pair and three bonded atoms. The lone pair repels the bonded atoms, causing bond angles to be slightly less than tetrahedral geometry, approximately 107 degrees<\/strong>, but never 120 degrees<\/strong>.<\/p>\n\n\n\n Trigonal planar geometry<\/strong> can exist with 120-degree bond angles<\/strong>, as seen in molecules with three bonded atoms and no lone pairs around a central atom. A trigonal planar structure cannot exhibit 109.5-degree bond angles<\/strong>, since such angles belong to tetrahedral molecules.<\/p>\n\n\n\n To summarize, tetrahedral geometry only has 109.5-degree bond angles<\/strong>. Trigonal planar molecules adopt 120-degree angles<\/strong>, and pyramidal geometry typically falls around 107 degrees<\/strong>, depending on lone pairs and repulsion forces. The correct molecular shape and bond angle must align with the number of bonded atoms and lone pairs affecting electron repulsion.<\/p>\n\n\n\n What is the shape and bond angle for tetrahedral shape; 120 bond angle tetrahedral shape; 109.5 bond angle tetrahedral shape; 90 bond angle pyramidal, 120 bond angle pyramidal, 109.5 bond angle trigonal planar; 120 bond angle trigonal planar; 109.5 bond angle The Correct Answer and Explanation is: The tetrahedral shape is characterized by four bonded […]<\/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-235573","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/235573","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=235573"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/235573\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=235573"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=235573"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=235573"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-603.jpeg\")
