Question

Соответствие между классом соединений, к которому вещество может принадлежать, и его формулой Предельная одноосновная карбоновая кислота С7Н8О Предельный альдегид С3Н8О2 Фенол С2Н6О Предельный одноатомный спирт С3Н6О

Answer 1

Предельная одноосновная карбоновая кислота - С3Н8О2;
Предельный альдегид - C3H6O;
Фенол - С7Н8О;
Предельный одноатомный спирт - С2Н6О.

Небольшая проблемка - С3Н6О2, но не C3H8O2.

Answer 2

Correspondence between the class of compounds and their formulas

The correspondence between the class of compounds and their formulas is as follows:

1. Saturated monocarboxylic acid (carboxylic acid): The formula for a saturated monocarboxylic acid is C7H8O. One example of a saturated monocarboxylic acid is benzoic acid (C6H5COOH) [[1]].

2. Saturated aldehyde: The formula for a saturated aldehyde is C3H8O2. One example of a saturated aldehyde is propanal (CH3CH2CHO) [[2]].

3. Phenol: The formula for phenol is C6H6O. Phenol is an aromatic compound that consists of a benzene ring with a hydroxyl group (-OH) attached to it [[3]].

4. Saturated monohydric alcohol (alcohol): The formula for a saturated monohydric alcohol is C3H6O. One example of a saturated monohydric alcohol is propanol (CH3CH2CH2OH) [[4]].

Please note that these are just a few examples of compounds belonging to each class. There are many other compounds that can belong to these classes as well.
