18.11.2020, adminCarbon can neither lose four of its electrons nor gain four electrons as both the processes require extra amount of energy and would 41 the system unstable. Therefore, it completes 4. octet by sharing its four electrons with other carbon atoms or with atoms of other elements. The bonds that are formed by sharing electrons are known as covalent bonds. In covalent bonding, both the atoms share the valence electrons, i. Exerciae, carbon requires 4 electrons to complete its octet, while each lcass atom requires one electron to complete its duplet.
Also, chlorine requires an electron to complete the octet. Therefore, all of these share the electrons and as a result, carbon forms 3 bonds with hydrogen and one with chlorine. A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group. For example, methane, ethane, propane, butane. How can ethanol and ethanoic acid be differentiated on the basis of their physical and chemical properties?
This is below room temperature and hence, it freezes during winters. Why does micelle formation take place when soap is added to water? Will a micelle be formed in other solvents such as ethanol also? Used diesel fishing boats for sale in florida ag soap is a sodium or potassium salt of long chain fatty acids. It has one polar end and one non-polar end. The polar end is hydrophilic in nature i.
The non-polar end is hydrophobic but lipophilic, i. When soap is added to water, soap molecules arrange themselves in a cluster ncert solutions class 10th exercise 4.1 china keep the non-polar portion out of water such that the non-polar ends are in the interior of the cluster and the polar ends used diesel fishing boats for sale in florida ag on the surface of the cluster.
Since the dirt present on clothes is organic in nature and insoluble in water, the hydrophobic ends of the clusters attach themselves to the dirt. This cluster formation in which the dirt is entrapped is the micelle. Micelle formation does not occur in alcohol because the alkyl chain of soap becomes soluble in alcohol. Most of the carbon compounds give a lot of heat and light when burnt in air.
Saturated hydrocarbons burn with a clean flame and no smoke is produced. The carbon compounds, used as a fuel, have high calorific values. Therefore, carbon and its compounds are used as fuels for most applications. Soap does not work properly when the water is hard. Hard water contains salts of calcium and magnesium.
When soap is added to hard water, calcium and magnesium ions present in water displace sodium or potassium ions from the soap molecules forming an insoluble substance called scum. A lot of soap is wasted chian the process. Since soap is basic in nature, it will turn red litmus blue. However, the colour of blue litmus will remain blue. Hydrogenation ncert solutions class 10th exercise 4.1 china the process of addition of hydrogen.
Unsaturated hydrocarbons are added with hydrogen in the presence of palladium and nickel catalysts to give saturated hydrocarbons. This reaction is applied in the hydrogenation of vegetables oils, which contain long chains of unsaturated carbons. Unsaturated hydrocarbons undergo addition reactions. Being unsaturated hydrocarbons, C 3 H 6 and C 2 H 2 undergo addition reactions. Butter contains saturated fats. Therefore, it cannot be hydrogenated. On the other hand, oil has unsaturated fats.
That is why it can be hydrogenated to saturated fats 10ty. Intext Exercise 4. Sorry, this phone number is not verified, Please login with your email Id. Post Your Requirement today and get connected.

Question 2: Used diesel fishing boats for sale in florida ag is a four-carbon compound with the functional group a carboxylic acid. Solution 2: c The functional group of butanone is ketone. Question ncert solutions class 10th exercise 4.1 china While cooking, if the bottom of the vessel is getting blackened on the outside, it means that ncert solutions class 10th exercise 4.1 china the food is not cooked completely.
Solution 3: b While cooking, if the bottom of the vessel is getting blackened on the outside, then it means that the fuel is not burning completely.
Question 4: Explain the nature of the covalent bond using the bond formation in CH 3 Cl. Solution 4: Carbon can neither lose four of its electrons nor gain four electrons as both the processes require extra amount of energy and would make the system unstable.
Question 5: Draw the electron dot structures for a ethanoic acid. Question 6: What is a homologous series? Explain with an example. Solution 6: A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group.
Question 7: How can ethanol and ethanoic acid be differentiated on the basis of their physical and chemical properties? Sollutions example, For example. Question 8: Why does micelle formation take place when soap is added to water? Solution 8: A soap is a sodium or potassium salt of long chain fatty acids. Question 9: Why are carbon and its compounds used as fuels for most applications? Solution 9: Most of the carbon compounds give a lot of heat and light when burnt in air. Question Explain the formation of scum when hard water is treated with soap.
Solution Soap does not work properly when the used diesel fishing boats for sale in florida ag is hard. Question What change will you observe if you test soap with litmus paper red and blue? Solution Since soap is basic in nature, it will turn red litmus blue. Question What is hydrogenation? What is its industrial application?
Solution Hydrogenation is the process of addition of hydrogen. Solution Unsaturated hydrocarbons undergo addition reactions. Question Give a test that can be used to differentiate chemically between butter and cooking oil. Solution Butter contains saturated fats. Question Explain the mechanism of the cleaning action of soaps.
