It is suitable for all categories of students and all Boards. But I would like to add that the NCERT books do not provide a comprehensive coverage of tricky questions and numerous riddles asked in exam papers.
For this purpose, subject reference books are also needed.

It increases their reasoning and logical thinking and sharpens problem-solving capability. According to the teachers, the question papers for board exams are formed from the NCERT textbooks and thus no student should forget reading these books at least once. So, a student who follows NCERT books will not have a problem if he or she shifts to another state because the syllabus is same anywhere.
This is not the case for other boards. At the end of the day, what matters is the knowledge a person has gained and what one has learned in their life. It does not matter in which board of education one has studied or which books one has used to prepare for the examination.
All the boards have different syllabus, rules and teaching style. The books preferred by these boards are easy for some while tough for others. Some have good teachers, lenient examination while some do not have these facilities.FORM 1 CHEMISTRY INTRODUCTION TO CHEMISTRY (1).mp4

The book concentrates on core topics which are most likely to be common to those organic chemistry courses which follow on from a foundation or introductory general chemistry course. This book attempts to condense the essentials of organic chemistry into a manageable text of pages which is student friendly and which does not cost an arm and a leg.
It does this by concentrating purely on the basics of the subject without going into exhaustive detail or repetitive examples. Furthermore, key notes at the start of each topic summarize the essential facts covered and help focus the mind on the essentials.
It is hoped that students will find this textbook useful in their studies and that once they have grasped what organic chemistry is all about they will read more widely and enter a truly exciting world of molecular science.Faragha Nasson Saturday, August 12, 0. Oxygen is mainly found in combined states as oxides, hydroxides, silicates, sulphates, carbonates, water, etc. Its ease of combination with other elements to form compounds shows that oxygen is a very reactive element.
Preparation and Properties of Oxygen. Oxygen can be prepared in the laboratory from either hydrogen peroxide solution or potassium chlorate salt. A Sample of Oxygen Gas in the Laboratory. The most common method for the preparation of oxygen in the laboratory is by decomposition of hydrogen peroxide solution. The gas is prepared by catalysing the decomposition of hydrogen peroxide with manganese IV oxide.
At room temperature hydrogen peroxide decomposes breaks down very slowly. It decomposes to water and oxygen. To speed up the decomposition process, and hence collect substantial amount of oxygen gas within a short time, black manganese IV oxide is added as a catalyst.
A catalyst is a substance that, although present in small quantities, will alter the rate of a chemical reaction but will remain chemically unchanged at the end of the reaction. Preparation method. Hydrogen peroxide 20 vol. Oxygen is collected over water as shown in figure bellow.
The gas is collected by downward displacement of water because it is only slightly soluble in water. Apparatus for laboratory preparation of oxygen from hydrogen peroxide solution. Oxygen can also be prepared by thermal decomposition of potassium chlorate. When this compound is heated, it decomposes slowly into potassium chloride and oxygen:.
A grinded mixture of potassium chlorate and manganese IV oxide, at a ratio ofis placed in hard glass tube and fitted up as shown in figure bellow.
The mixture is then heated and oxygen gas is readily given off. The gas is collected over water. Oxygen has almost the same density as air, so it cannot be collected by the upward displacement of air.
It is possible to collect it by downward displacement of water as shown in the figure because it is only slightly soluble in water. Apparatus for laboratory preparation of oxygen from potassium chlorate. Test for oxygen. Oxygen rekindles a glowing splint of wood. No gases behave like this except dinitrogen oxide, NO 2from which oxygen can be distinguished by the following properties:.
Oxygen has no smell but dinitrogen oxide has a sweet, sickly smell. When heated with nitrogen monoxide, oxygen produces brown fumes of nitrogen dioxide. Dinitrogen oxide has no effect on nitrogen monoxide.
Perform simple experiments to demonstrate properties of oxygen gas. Action of oxygen on metals. The manner in which oxygen reacts with metals is summarized in the list below.
Reaction with specific metals. When burnt in excess of oxygen, sodium burns with an intense yellow flame to give sodium peroxide. The product is a yellow solid which dissolves in water to give an alkaline solution. The metal burns in air with a red flame giving a white solid of calcium oxide:.Home About Contact.
