Modern NCERT Class 11 Chemistry Syllabus, dating more or less from the late 18th-century acceptance of the law of mass conservation, initially focused on those substances not associated with living organisms. The discipline of inorganic chemistry is the study of such substances, which normally have little or no carbon. Early work sought to identify the simple substances that are the constituents of all the more complex substances, namely the elements. Some elements have been known since ancient times, such as gold and carbon, and many others have been discovered and studied during the 19th and early 20th centuries. Over 100 are known today. The study of such simple inorganic compounds as sodium chloride (common salt) has led to some of modern chemistry's fundamental concepts, with one notable example being the law of certain proportions. In this law, the constituent elements are always present in fixed proportions by mass for most pure chemical substances (e.g., every 100 grams of salt contains 39.3 grams of sodium and 60.7 grams of chlorine). The crystalline salt form, known as halite, is made up of mixed sodium and chlorine atoms, one sodium atom per chlorine. Such a compound is known as a binary compound, formed solely by the combination of two elements. In inorganic chemistry, binary compounds are very common and show little structural variety. For this reason, despite a large number of elements that can react with each other, the number of inorganic compounds is limited. Combining three or more elements in a substance increases the structural possibilities. The NCERT Class 11 Chemistry Syllabus study matter is on the Extramarks website.

Inorganic chemistry has again become an exciting area of research after a period of quiescence in the early part of the 20th century. Boron and hydrogen compounds, known as boranes, have unique structural characteristics that forced a change in thinking about inorganic molecules architecture. Some inorganic substances have long-established structural features in carbon compounds alone, and some inorganic polymers have even been produced. Ceramics are materials combined with oxygen composed of inorganic elements. Ceramic objects were made by heating a vessel formed from a paste of powdered minerals strongly for centuries. Although ceramics at very high temperatures are quite hard and stable, they are usually fragile. New ceramics are currently being produced strong enough to be used as turbine blades in jet engines. Ceramics are hoped to one day replace steel in internal-combustion engine components. A ceramic containing yttrium, barium, copper, and oxygen with the approximate YBa2Cu3O7 formula was found to be a superconductor at a temperature of about 100 Kin 1987. A superconductor offers no resistance to an electrical current's passage, and this new type of ceramic could very well find wide use in electrical and magnetic applications. It is so simple to make a superconducting ceramic that it can be prepared in a high school lab. His discovery illustrates the unpredictability of chemistry, for fundamental discoveries with simple equipment and cheap materials can still be made.
