Task 1: "True or False" Statements about Alcohols and Carboxylic Acids:

1. Alcohols are organic compounds that contain a hydroxyl group. True. Alcohols are organic compounds that contain a hydroxyl (-OH) group [[1]]. 2. Monohydric alcohols contain one hydroxyl group. True. Monohydric alcohols, as the name suggests, contain one hydroxyl group [[2]]. 3. Glycerol belongs to the group of monohydric alcohols. False. Glycerol, also known as glycerin, is a trihydric alcohol because it contains three hydroxyl groups [[3]]. 4. The common property of alcohols is their ability to burn. True. Alcohols, including ethanol, can burn as they are flammable substances [[4]]. 5. Glycerin can be used in the production of ointments. True. Glycerin has moisturizing properties and is commonly used in the production of ointments and creams [[5]]. 6. Ethanol and glycerol are used in perfumery. True. Ethanol (also known as ethyl alcohol) and glycerol are commonly used in the perfume industry as solvents and fragrance carriers [[6]]. 7. Methanol belongs to the group of polyhydric alcohols. False. Methanol is a monohydric alcohol because it contains only one hydroxyl group [[7]]. 8. Methanol is a toxic substance. True. Methanol is toxic and can cause severe health effects if ingested or inhaled [[8]]. 9. Glycerol is a trihydric alcohol. True. Glycerol, also known as glycerin, is a trihydric alcohol because it contains three hydroxyl groups [[3]]. 10. The formula of ethanol is CH3OH. False. The formula of ethanol is C2H5OH [[9]]. 11. Glycerol and ethanol are soluble in water. True. Both glycerol and ethanol are soluble in water [[10]].

Task 2: Structural Formulas of Alcohols and Carboxylic Acids:

- Methanol: CH3OH - Ethanol: C2H5OH - Ethylene glycol (ethanediol): HOCH2CH2OH - Hexanoic acid: CH3(CH2)4COOH - Pentanoic acid: CH3(CH2)3COOH

Please note that the structural formulas provided above are simplified representations and may not include all the necessary bonds and atoms.
