A molecule containing only carbon and hydrogen<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>Hydrocarbons are organic compounds primarily made up of hydrogen and carbon atoms. They serve as the foundational building blocks of organic chemistry and are crucial to various natural processes and industries. Hydrocarbons can be categorized into two main types: <strong>aliphatic hydrocarbons<\/strong> and <strong>aromatic hydrocarbons<\/strong>.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Aliphatic Hydrocarbons<\/strong>: These hydrocarbons can be further divided into three subclasses:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Alkanes<\/strong>: These are saturated hydrocarbons, meaning they contain single bonds between carbon atoms. The general formula for alkanes is ( C_nH_{2n+2} ), where ( n ) is the number of carbon atoms. Examples include methane (CH\u2084) and propane (C\u2083H\u2088).<\/li>\n\n\n\n<li><strong>Alkenes<\/strong>: These are unsaturated hydrocarbons that contain at least one double bond between carbon atoms. Their general formula is ( C_nH_{2n} ). An example of an alkene is ethylene (C\u2082H\u2084).<\/li>\n\n\n\n<li><strong>Alkynes<\/strong>: These also are unsaturated but contain at least one triple bond between carbon atoms, with the general formula ( C_nH_{2n-2} ). An example is acetylene (C\u2082H\u2082).<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Aromatic Hydrocarbons<\/strong>: These hydrocarbons contain one or more aromatic rings, which are cyclic structures with alternating single and double bonds. Benzene (C\u2086H\u2086) is a classic example of an aromatic hydrocarbon.<\/li>\n<\/ol>\n\n\n\n<p>Hydrocarbons are essential in various applications, including fuel (gasoline, diesel), lubricants, and the production of chemicals and plastics. Their properties can vary significantly based on their structure; for instance, alkanes tend to be less reactive than alkenes and alkynes due to their saturated nature.<\/p>\n\n\n\n<p>In summary, hydrocarbons are molecules consisting solely of carbon and hydrogen, forming the basis for many organic substances and playing a vital role in energy and materials industries.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is a hydrocarbon?A.
