An alcohol that has 2 hydroxyl groups includes which of the following in its name?<\/p>\n\n\n\n
-ene <\/p>\n\n\n\n
-diol <\/p>\n\n\n\n
-triol <\/p>\n\n\n\n
-ane<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is -diol<\/strong>.<\/p>\n\n\n\n Explanation: When naming alcohols, the suffix used depends on the number of hydroxyl groups present in the molecule. A basic alcohol with one hydroxyl group at the end of the carbon chain is named by adding the suffix -ol<\/strong> to the root name of the hydrocarbon chain.<\/p>\n\n\n\n If the alcohol contains two hydroxyl groups, the suffix -diol<\/strong> is used. The di-<\/strong> prefix indicates that there are two hydroxyl groups. A good example of this is ethylene glycol (also known as ethane-1,2-diol), which is a two-hydroxy alcohol.<\/p>\n\n\n\n For alcohols with three hydroxyl groups, the suffix -triol<\/strong> is used, such as in glycerol (propane-1,2,3-triol). This naming convention helps distinguish alcohols based on the number of hydroxyl groups they contain.<\/p>\n\n\n\n The suffix -ene<\/strong> is used to indicate the presence of a double bond in the molecule, which is unrelated to the number of hydroxyl groups. Similarly, -ane<\/strong> is used for alkanes, hydrocarbons that contain only single bonds, and is also not relevant to alcohols with hydroxyl groups.<\/p>\n\n\n\n Therefore, alcohols with two hydroxyl groups are always named with the -diol<\/strong> suffix, which accurately reflects their structure. This helps to ensure clarity in chemical nomenclature, making it easier to understand the molecular composition of organic compounds.<\/p>\n","protected":false},"excerpt":{"rendered":" An alcohol that has 2 hydroxyl groups includes which of the following in its name? -ene -diol -triol -ane The correct answer and explanation is: The correct answer is -diol.

Alcohols are organic compounds characterized by the presence of one or more hydroxyl (-OH) groups attached to a carbon atom. The nomenclature of alcohols follows a set of rules established by the International Union of Pure and Applied Chemistry (IUPAC).<\/p>\n\n\n\n
