However the electrophile is a molecule that attracted to the electron-rich double bond.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Markovnikovs_rule\"><\/span>Markovnikov\u2019s rule<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>Markovnikov\u2019s rule states that in an electrophilic addition reaction, the electrophile will add to the carbon atom that has more hydrogen atoms attached to it. This rule named after Russian chemist Vladimir Markovnikov, who first proposed it in 1869.<\/li>\n<li>In an addition reaction, two molecules collide and join together to form a new molecule. This process is also known as a molecular reaction. For example, when two hydrogen atoms collide, they join together to form a molecule of hydrogen gas.<\/li>\n<li>In more complicated cases, the two molecules may be different types of atoms or molecules. For example, when a molecule of hydrogen gas collides with a molecule of oxygen gas, they join together to form a molecule of water.<\/li>\n<li>In an additional reaction, the two molecules must collide in order to join together. If the molecules do not collide, then the reaction will not occur. This is why addition reactions only occur at very high temperatures or under very high pressures.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Introduction\"><\/span><strong><span style=\"font-size: 18pt;\">Introduction<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Inorganic chemistry, addition reactions are those in which two or more molecules join together to form a larger molecule.<\/li>\n<li>The cyclopropane ring formation reaction is a type of addition reaction in which a molecule of carbon monoxide added to an alkyne to form a cyclopropane ring. This reaction shown in equation 1.<\/li>\n<li>Therefore the hydrogenation of alkyne is a type of addition reaction in which a molecule of hydrogen added to an alkyne to form a hydrocarbon. This reaction shown in equation 2.<\/li>\n<li>The purpose of this essay is to discuss the mechanisms of the cyclopropane ring formation reaction and the hydrogenation of alkyne.

Therefore the reduction of alkynes the second step of the process, where the alkyne molecules reduced to alkanes.
