The alcohol content of hard liquor is normally given in terms of the "proof." which is defined as twice the percentage by volume of ethanol (C2H5OH) present. Calculate the number of grams of alcohol present in 1.00 L of 75-proof gin. The density of ethanol is 0.798 g/mL.
Chapter 13 Notes Alcohol -Alcohols are determined by the hydroxyl group -OH -The -OH replaces a Hydrogen atom in a Hydrocarbon molecule -Naming Alcohols, remove the Alkane ending and replace it with -ol. If a Hydrocarbon molecule has two -OH groups attached, it is called a Diol. If a molecule has three -OH groups attached, it is called a Triol. Primary Alcohol (1 ) Secondary Alcohol (2 )o Tertiary Alcohol (3 ) The primary Carbon atom The primary Carbon atom The primary Carbon atom that is attached to the that is attached to the that is attached to the -OH group is connected to -OH group is attached to -OH group is attached to only one other Carbon only two other Carbon three o
