We look for a chemical shift to identify a chemical attribute. A chemical change always results in the formation of one or more types of matter that are distinct from the matter that existed before to the change.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Combustion Reactions<\/h3>\n\n\n\n<p>Combustion means burning of carbon or carbon-containing compounds in the presence of air or oxygen to produce carbon dioxide, heat and light.<\/p>\n\n\n\n<p><strong>2CH<sub>3<\/sub>OH + 3O<sub>2<\/sub>&nbsp;\u2192 4H<sub>2<\/sub>O + 2CO<sub>2<\/sub><\/strong><\/p>\n\n\n\n<p>For example,<\/p>\n\n\n\n<p>Naphthalene also undergoes combustion in the presence of oxygen to afford carbon dioxide gas and water. The chemical equation for this reaction is given by:<\/p>\n\n\n\n<p><strong>12O<sub>2<\/sub>&nbsp;+ C<sub>10<\/sub>H<sub>8<\/sub>&nbsp;\u2192 4H<sub>2<\/sub>O + 10CO<sub>2<\/sub><\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Flame Characteristics<\/h3>\n\n\n\n<p>Saturated hydrocarbons give clean flame while unsaturated hydrocarbons give smoky flame. In the presence of limited&nbsp;oxygen, even saturated hydrocarbons give smoky flame.<\/p>\n\n\n\n<p>A black substance formed by combustion or separated from fuel during combustion, rising in fine particles, and adhering to the sides of the chimney or pipe conveying the smoke especially : the fine powder consisting chiefly of carbon that colors smoke called soot.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Oxidation<\/h3>\n\n\n\n<p>Oxidation is a chemical reaction that occurs in an atom or compound and results in the loss of one or more electrons.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/cdn1.byjus.com\/wp-content\/uploads\/2020\/02\/CBSE-Notes-Class-10-Science-Chapter-4-18.gif\" alt=\"Carbon-and-Its-Compounds-17\" title=\"Carbon-and-Its-Compounds-17\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Addition<\/h3>\n\n\n\n<p>The reactions in which two molecules react to form a single product having all the atoms of the combining molecules are called addition reactions.<br>The hydrogenation reaction is an example of the addition reaction. In this reaction, hydrogen is added to a double bond or a triple bond&nbsp;in the presence of a catalyst like nickel, palladium or platinum.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/cdn1.byjus.com\/wp-content\/uploads\/2020\/02\/CBSE-Notes-Class-10-Science-Chapter-4-19.gif\" alt=\"Carbon-and-Its-Compounds-18\" title=\"Carbon-and-Its-Compounds-18\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Substitution<\/h3>\n\n\n\n<p>The reaction in which an atom or group of atoms in a molecule is replaced or substituted by different atoms or group of atoms is called substitution reaction.&nbsp;In alkanes, hydrogen atoms are replaced by other elements.<\/p>\n\n\n\n<p>CH<sub>4<\/sub>+Cl<sub>2<\/sub>+Sunlight \u2192 CH<sub>3<\/sub>Cl+HCl<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The members of any particular family have almost identical chemical properties due to the same functional group.&nbsp;Their physical properties such as melting point, boiling point, density, etc., show a regular gradation with the increase in the molecular mass.
