Most . concentrated. source of food energy. Provide . Learning Objectives:. Know the general formula for alcohols.. Be able to name alcohols.. Describe the shape of alcohols.. Classify primary, secondary, and tertiary alcohols.. Describe the physical properties of alcohols.. Alcohol . – alkyl chain attached to an –OH. . R-OH. Phenol . - aromatic attached to an –OH. Nomenclature. 1. Name the longest chain of carbons which includes the carbon with the hydroxyl group.. Learning Objectives. Learn what a triglyceride is.. Learn what a fatty acid is.. Learn the structure of a . phospholipid. .. Learn how lipids are tested for.. What is a lipid?. Like most other biochemical substances, lipids contain . PHENOLS. Alcohols and Phenols. Alcohols contain an OH group connected to a . a. saturated C (sp. 3. ). They are important solvents and synthesis intermediates. Phenols contain an OH group connected to a carbon in a benzene ring. 1. Hydration of Alkenes - . addition of water. - uses H. 2. SO. 4. and heat. Ex.; Hydrate propene.. 2. Hydrogenation of Aldehydes & Ketones –. All . carbon-carbon double bonds in the molecule will be hydrogenated at the same time. nonpolar. organic compound insoluble in polar solvent , but . soluble in organic solvents. such as benzene ,ether, chloroform.. Biological role of lipids. :. Lipids are found naturally in all living organisms.. st. 1439 . Learning. . Objectives. By the end of this chapter the student will:. . know the structure of alcohol. Knew the different classes of alcohols.. Knew the nomenclature of Alcohols . Knew the physical Properties. . are a diverse group of compounds that are insoluble in water but soluble in organic solvents such as ethanol.. The most common types of lipid are . triglycerides. (sometimes known as true fats or neutral fats), but other important lipids include waxes, steroids and cholesterol.. Most of the alcohols are known to be . colourless. liquids or even are said to behave as solid at room temperatures. Alcohols with less molecular weight are said to be highly soluble in water; and with their increase in molecular weight, they tend to become less soluble and their .
