FAQs on JEE Main 2025 Mock Test: Organic Compounds Containing Oxygen Preparation
1. What are organic compounds containing oxygen?
Organic compounds containing oxygen are chemical compounds made mainly of carbon (C), hydrogen (H), and oxygen (O) atoms. These include important classes like alcohols, ethers, aldehydes, ketones, carboxylic acids, and esters, which play key roles in both biological and industrial processes.
2. What are the different types of oxygen-containing organic compounds?
The most common types of oxygen-containing organic compounds include:
1. Alcohols (contain the -OH group);
2. Ethers (contain -O- linkage);
3. Aldehydes (contain -CHO group);
4. Ketones (contain >C=O group in the middle of carbon chain);
5. Carboxylic acids (contain -COOH group); and
6. Esters (contain -COOR group). These functional groups determine their chemical and physical properties.
3. How are alcohols classified?
Alcohols are classified based on the number of alkyl groups attached to the carbon atom bonded with the hydroxyl group (-OH) as:
- Primary (1°) Alcohols: -OH group attached to a carbon atom bonded with one alkyl group.
- Secondary (2°) Alcohols: -OH group attached to a carbon atom bonded with two alkyl groups.
- Tertiary (3°) Alcohols: -OH group attached to a carbon atom bonded with three alkyl groups.
4. What is the difference between aldehydes and ketones?
The main difference is in the position of the carbonyl group (C=O):
- Aldehydes have the carbonyl group at the end of the carbon chain and have general formula R-CHO.
- Ketones have the carbonyl group within the carbon chain (not on the end), with formula R-CO-R' where both R and R' are alkyl groups.
5. Why are carboxylic acids acidic in nature?
Carboxylic acids are acidic because their carboxyl group (-COOH) can easily donate a proton (H+) to a base due to the resonance stabilization of the resulting carboxylate ion (-COO-). This property makes carboxylic acids stronger acids than alcohols or phenols.
6. What are the uses of ethers in daily life?
Ethers have various important uses due to their properties:
- Used as solvents in laboratories and industries because they dissolve non-polar substances.
- Previously used as an anesthetic in surgeries (diethyl ether).
- Found in some pharmaceuticals and as fuel additives (MTBE).
7. How can alcohols be prepared from aldehydes and ketones?
Alcohols can be prepared by the reduction of aldehydes or ketones:
- Aldehydes on reduction give primary alcohols.
- Ketones on reduction give secondary alcohols.
8. What is the IUPAC naming rule for carboxylic acids?
The IUPAC name for a carboxylic acid is given by replacing the ‘e’ of the parent alkane with ‘oic acid’. For example:
- ‘Methane’ becomes methanoic acid
- ‘Ethane’ becomes ethanoic acid
9. How do you test for the presence of aldehydes?
The presence of aldehydes can be tested by:
- Tollen’s test: Aldehydes reduce Tollen’s reagent to produce a silver mirror.
- Fehling’s test: Aldehydes reduce Fehling’s solution to form a red precipitate of copper(I) oxide.
10. What are esters and where are they found?
Esters are organic compounds derived from carboxylic acids and alcohols, with a general formula RCOOR'. They are responsible for the pleasant fragrances and flavors in fruits and flowers and are used in perfumes, flavorings, and synthetic fibers.
11. What are the physical properties of alcohols?
Alcohols generally show:
- Higher boiling points than similar molecular mass alkanes due to hydrogen bonding
- Solubility in water: Lower alcohols are highly soluble owing to the presence of the -OH group
- Colorless and typically possess a characteristic odor
12. What is the functional group in ethers and how is it represented?
Ethers contain the ether functional group or alkoxy group which is represented as R-O-R’, where R and R' are alkyl or aryl groups. This group imparts unique physical and chemical properties to ethers, such as low reactivity and volatility.
