FAQs on JEE Main 2025-26 Mock Test: Practice Organic Compounds Containing Oxygen
1. What are organic compounds containing oxygen?
Organic compounds containing oxygen are chemical compounds that include at least one atom of oxygen in addition to carbon and hydrogen. Common types include alcohols, phenols, ethers, aldehydes, ketones, carboxylic acids, and their derivatives. These compounds are fundamental in biochemistry and industry, and their properties are influenced by the presence and type of oxygen-containing functional group.
2. What are the different classes of organic compounds containing oxygen?
The major classes of organic compounds containing oxygen are:
• Alcohols (–OH group);
• Phenols (aromatic –OH group);
• Ethers (R–O–R’);
• Aldehydes (–CHO group);
• Ketones (C=O group in the middle of a chain);
• Carboxylic acids (–COOH);
• Esters, anhydrides, and acid chlorides are carboxylic acid derivatives. Each class has unique properties and uses.
3. What is the difference between alcohols and phenols?
The primary difference lies in their structure and properties: Alcohols have a hydroxyl (–OH) group attached to a saturated carbon, while phenols have the –OH group attached to an aromatic ring. Phenols are usually more acidic than alcohols due to resonance stabilization of their conjugate base.
4. How are aldehydes and ketones different?
Both aldehydes and ketones contain a carbonyl group (C=O). In aldehydes, the carbonyl group is attached to at least one hydrogen atom and is always at the end of the carbon chain. In ketones, the carbonyl group is bonded to two carbon atoms and is present within the carbon chain.
5. What are carboxylic acids and their derivatives?
Carboxylic acids are organic compounds containing the carboxyl group (–COOH). Their derivatives include esters, acid chlorides, anhydrides, and amides, all of which are formed by replacing the hydroxyl group of a carboxylic acid with another group.
6. How are ethers named according to the IUPAC system?
In the IUPAC nomenclature, ethers are named as 'alkoxy alkanes.' The shorter alkyl group bonded to oxygen forms the alkoxy prefix, followed by the name of the longer alkane chain. For example, methoxyethane for CH3OCH2CH3.
7. What types of reactions are commonly seen with alcohols?
Alcohols undergo a variety of reactions such as:
• Oxidation (to aldehydes, ketones, or acids);
• Dehydration (to form alkenes);
• Substitution (to form ethers or halides);
• Esterification (with acids to form esters).
8. Why are phenols more acidic than alcohols?
Phenols are more acidic than alcohols because the negative charge on the phenoxide ion (after losing a proton) is stabilized by resonance within the aromatic ring, making it easier for phenol to lose a hydrogen ion compared to alcohols.
9. What test is used to distinguish between aldehydes and ketones?
The Tollen’s test and Fehling’s test are commonly used to distinguish between aldehydes and ketones. Aldehydes give a positive result (silver mirror or red precipitate), while ketones do not react due to the absence of hydrogen directly bonded to the carbonyl carbon.
10. What happens when carboxylic acids react with bases?
When carboxylic acids react with bases (like NaOH), they undergo a neutralization reaction to form a carboxylate salt and water. For example: CH3COOH + NaOH → CH3COONa + H2O.
11. How can you prepare esters from carboxylic acids?
Esters can be prepared by reacting carboxylic acids with alcohols in the presence of an acid catalyst (usually concentrated H2SO4), a process called esterification. This reaction produces an ester and water.
12. What is the role of oxygen-containing organic compounds in daily life?
Oxygen-containing organic compounds play vital roles in everyday life. For example:
• Alcohols are used as antiseptics and solvents;
• Phenols are ingredients in disinfectants;
• Carboxylic acids like acetic acid are used in food preservation;
• Aldehydes and ketones are found in fragrances and solvents;
• Esters provide fruity aromas and flavors.
