1. What is the general formula for carboxylic acids? a) b) o) c) r-oh; r-c; r-cooh; r1-o-r2 h 2. The functional group

Carboxylic acids
Пояснение: Carboxylic acids are organic compounds that contain the carboxyl functional group (-COOH). The general formula for carboxylic acids is R-COOH, where R represents any alkyl or aryl group. In this formula, the R group determines the specific compound.

Доп. материал: Use the general formula for carboxylic acids to identify the correct option in the given task. The correct answer is c) r-cooh, which represents the carboxylic acid structure.

Совет: To understand carboxylic acids better, it"s important to learn about functional groups in organic chemistry and familiarize yourself with different types of compounds. Practice identifying carboxylic acids from their molecular formulas and study their properties and reactions.

Ещё задача: Provide the correct name for the compound with the molecular formula CH3-COO-CH2CH3.

Functional group -on
Пояснение: The functional group -on belongs to the class of substances called aldehydes. Aldehydes have the general structure R-CHO, where R represents any alkyl or aryl group. The -on functional group indicates the presence of a carbonyl group bonded to at least one hydrogen atom.

Доп. материал: Identify the correct option in the given task. The correct answer is a) aldehydes, as the functional group -on is characteristic of this class of substances.

Совет: To understand the different classes of organic compounds, it"s helpful to study their functional groups and their respective properties and reactions. Practice recognizing the functional groups in molecular formulas and relate them to their corresponding classes.

Type of isomerism characteristic for monatomic alcohols
Пояснение: The type of isomerism characteristic for monatomic alcohols is spatial (stereo isomerism). Stereo isomerism occurs when compounds have the same molecular formula and connectivity but differ in the arrangement of atoms in space. In the case of monatomic alcohols, such as ethanol (C2H5OH), isomers can exist due to the presence of chiral carbon atoms.

Доп. материал: Determine the correct option in the given task. The correct answer is b) spatial (stereo isomerism).

Совет: To understand stereo isomerism, learn about chiral carbon atoms, enantiomers, and optical activity. Practice identifying chiral centers in compounds and determining if they have stereoisomers.

Ещё задача: How many stereoisomers can exist for a compound with the molecular formula C3H8O?
