We can distinguish between alcohol and carboxylic acid by reacting them with carbonates/hydrogen carbonates. The acid reacts with hydrogen carbonate to liberate carbon dioxide which turns lime water milky.

CH_3COOH + NaHCO_3 \rightarrow CH_3COONa + CO_2 + H_2O

Whereas alcohol shows no evolution of gas when reacted with carbonates.

C_2H_5OH + NaHCO_3 \rightarrow no\ reaction

Q.2. What are oxidizing agents?

Answer:

The oxidation reaction is the reaction in which oxygen is added or hydrogen is removed.

The substance which adds oxygen to others is known as oxidizing agents.

Q. 4. Explain the nature of the covalent bond using the bond formation in.

Answer:

Carbon has four electrons in its outermost shell and needs to gain or lose four electrons to attain noble gas configuration. Carbon overcomes this problem by sharing its valence electrons with other atoms of carbon or with atoms of other elements.

Of the four electrons, three are shared with hydrogen atoms and one with a chlorine atom. Thus it has three (C-H) and one (C-Cl) covalent bonds.

These bonds formed by the sharing of electrons are known as covalent bonds. Carbon, hydrogen, and chlorine attains the nearest noble gas configuration of Ne, He and Ar respectively.

Answer:

Physical Properties

Ethanol Ethanoic acid
It has a pleasant smell. It has a pungent smell of vinegar.
It has a low boiling point : 351 K. It has a comparatively high boiling point: 391 K.

Chemical Properties:

Ethanol Ethanoic acid
It has no action on litmus paper. It turns blue litmus to red.
no reaction with NaHCO_3 Liberates CO_2 when reacted with NaHCO_3


Q. 8. Why does micelle formation take place when soap is added to water? Will a micelle be formed in other solvents such as ethanol also?

Answer:

A soap is a sodium or potassium salt of long-chain fatty acids. It has one polar hydrophilic end and one non-polar hydrophobic end. These molecules have a unique orientation inside water in form of clusters of molecule in which hydrophobic ends are in the interior of the cluster and ionic ends on the surface of cluster thus keeping the hydrocarbon portion out of water. This formation is known as Micelle. Soap in the form of a micelle is able to clean, as the oily dirt is collected in the centre of the micelle.

No, micelle formation does not take place in ethanol because the alkyl chain of soap becomes soluble in alcohol.

Q. 9. Why are carbon and its compounds used as fuels for most applications?

Answer:

Carbon compounds have high calorific values. Therefore, carbon and its compounds are used as fuels for most applications. They give a lot of heat and light when burnt in air. Saturated hydrocarbons like methane burn with a clean flame without any smoke and are thus environmentally friendly.

Class 10 Science Ch 4 NCERT Solutions

Q. 10. Explain the formation of scum when hard water is treated with soap.

Answer:

Hard water contains calcium and magnesium salts. When soap is added with hard water, it reacts with the calcium and magnesium ions of hard water to form an insoluble substance called scum. To overcome this problem, detergents are used.

Q. 11. What change will you observe if you test soap with litmus paper (red and blue)?

Answer:

Soap is basic in nature and hence will turn red litmus blue. However it will have no effect on blue litmus paper.

Q. 12. What is hydrogenation? What is its industrial application?

Answer:

The conversion of unsaturated hydrocarbon to saturated hydrocarbon by the addition of hydrogen in the presence of nickel catalyst is called hydrogenation. This reaction is commonly used in hydrogenation of vegetable oil into vegetable ghee.

Q. 13. Which of the following hydrocarbons undergo addition reactions:

  • C_{2}H_{6}, C_{3}H_{8}, C_{3}H_{6}, C_{2}H_{2}\; and\: CH_{4}.

Answer:

Unsaturated hydrocarbons like alkenes and alkynes will undergo addition reactions. Therefore, C_3H_6 (alkene having -C=C- ) and C_2H_2 (alkyne having -C\equiv C- ) will give addition reactions.

Q. 14. Give a test that can be used to differentiate between saturated and unsaturated hydrocarbons.

Answer:

Butter is a saturated compound and oil is an unsaturated compound.

Test: When oil is added to a test tube containing alkaline potassium permanganate solution KMnO_4 , the pink colour of the solution disappear. Therefore, cooking oil causes decolourisation of the solution. This does not happen in case of butter.

Q. 15. Explain the mechanism of the cleaning action of soaps.

Answer:

A soap is a sodium or potassium salt of long-chain fatty acids. It has one polar hydrophilic end and one non-polar hydrophobic end. When soap is at the surface of the water, the hydrophobic tail of soap being nonsoluble in water protrudes out of the water with the ionic end in water.

When there is no more space for soap molecules on the surface, these molecules create a unique orientation inside water in form of clusters in which hydrophobic ends are in the interior of the cluster and ionic ends on the surface of cluster thus keeping the hydrocarbon portion out of water. This formation is known as Micelle.

Soap in the form of a micelle is able to clean, as the oily dirt is collected in the centre of the micelle.The ionic ends in the micelles remain attached to water. When the dirty clothes are agitated in a soap solution, the oily dirt particles entrapped by soap micelles get dispersed in water and the clothes get cleaned.

The eligibility age criteria for class 10th CBSE is 14 years of age. Since your son will be 15 years of age in 2024, he will be eligible to give the exam.

That totally depends on what you are aiming for. The replacement of marks of additional subjects and the main subject is not like you will get the marks of IT on your Hindi section. It runs like when you calculate your total percentage you have got, you can replace your lowest marks of the main subjects from the marks of the additional subject since CBSE schools goes for the best five marks for the calculation of final percentage of the students.

However, for the admission procedures in different schools after 10th, it depends on the schools to consider the percentage of main five subjects or the best five subjects to admit the student in their schools.
