There are two main types: <strong>homolytic<\/strong> and <strong>heterolytic<\/strong>. In <strong>homolytic cleavage<\/strong>, the bond breaks evenly, and each atom retains one of the shared electrons, producing <strong>radicals<\/strong>, which are species with unpaired electrons. In contrast, <strong>heterolytic cleavage<\/strong> results in the formation of ions, where one atom retains both bonding electrons.<\/p>\n\n\n\n<p>For <strong>Question 3<\/strong>, the reaction shows hydrogen peroxide (HOOH) breaking into two hydroxyl radicals (HO\u2022), each with an unpaired electron. This clearly indicates <strong>homolytic cleavage<\/strong>. Therefore, the correct answer is <strong>A. homolytic<\/strong>.<\/p>\n\n\n\n<p><strong>Question 4<\/strong> follows directly from this concept\u2014<strong>homolytic cleavage<\/strong> produces <strong>radicals<\/strong>, not ions. Hence, the answer is <strong>B. radicals<\/strong>.<\/p>\n\n\n\n<p>In <strong>Question 5<\/strong>, the reaction converts one molecule (HOOH) into two particles (HO\u2022), increasing the number of molecules and disorder. This leads to an increase in entropy (\u0394S &gt; 0). So the sign of <strong>\u0394S<\/strong> is <strong>positive<\/strong>.<\/p>\n\n\n\n<p><strong>Question 6<\/strong> deals with <strong>Gibbs free energy change<\/strong> (\u0394G), which determines the spontaneity of a reaction. The formula is: \u0394G=\u0394H\u2212T\u0394S\\Delta G = \\Delta H &#8211; T\\Delta S<\/p>\n\n\n\n<p>For an <strong>exothermic reaction<\/strong> (\u0394H &lt; 0) with an <strong>increase in entropy<\/strong> (\u0394S &gt; 0), both terms favor a <strong>negative \u0394G<\/strong>, which means the reaction is <strong>spontaneous<\/strong>. Therefore, the correct answer is <strong>B. negative<\/strong>.<\/p>\n\n\n\n<p>Understanding these fundamental thermodynamic and chemical concepts is essential for predicting reaction mechanisms and behaviors in chemical systems.<\/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-banner4-198.jpeg\" alt=\"\" class=\"wp-image-222382\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Question 3: What type of bond cleavage does the following reaction involve?
