Unit 1: Some Basic Concepts of Chemistry
Chemistry deals with the composition, structure and properties of matter. These aspects can be described and understood in terms of basic constituents of matter: atoms and molecules. That is why chemistry is called the science of atoms and molecules.
Can we see, weigh and perceive these entities? Is it possible to count the number of atoms and molecules in a given mass of matter and have a quantitative relationship between the mass and number of these particles (atoms and molecules)?
You will like to answer some of these questions in this Unit of Jharkhand Board Class 11 Chemistry Syllabus. We would further describe how physical properties of matter can be quantitatively described using numerical values with suitable units.

Unit 4: Chemical Bonding and Molecular Structure
Matter is made up of one or different type of elements. Under normal conditions no other element exists as an independent atom in nature, except noble gases.
However, a group of atoms is found to exist together as one species having characteristic properties. Such a group of atoms in called a molecule. The force which holds these constituent atoms together is called chemical bond. This Unit of Class 11 Chemistry NCERT Syllabus is all about concepts of chemical bonding.

Unit 6: Thermodynamics
Chemical energy stored by molecules can be released as heat during chemical reactions when a fuel like methane, cooking gas or coal burn in air. The chemical energy may also be used to do mechanical work when a fuel burns in an engine or to provide electrical energy through galvanic cell like dry cell.
Thus, various forms of energy are interrelated and under certain conditions, these may be transformed from one form into another. The study of these energy transformations forms the subject matter of thermodynamics.
In this Unit of Jharkhand Board Intermediate First Year Class 11 Chemistry Syllabus , we would like to answer some of the important questions through thermodynamics, like: How do we determine the energy changes involved in a chemical reaction/process? What drives a chemical reaction/process? To what extent do the chemical reactions proceed?

Unit 10: The s-Block Elements
The s-block elements of the Periodic Table are those in which the last electron enters the outermost s-orbital. As the s-orbital can accommodate only two electrons, two groups (1 & 2) belong to the s-block of the Periodic Table.
Group 1 of the Periodic Table consists of the elements: lithium, sodium, potassium, rubidium, caesium and francium. They are collectively known as the alkali metals. These are so called because they form hydroxides on reaction with water which are strongly alkaline in nature.
The elements of Group 2 include beryllium, magnesium, calcium, strontium, barium and radium. These elements with the exception of beryllium are commonly known as the alkaline earth metals.
These are so called because their oxides and hydroxides are alkaline in nature and these metal oxides are found in the earth’s crust. This Unit of Jharkhand Board NCERT Class 11 Chemistry Syllabus is all about alkali metals and alkaline earth metals.

Unit 11: The p-Block Elements
In p-block elements the last electron enters the outermost p orbital. As we know that the number of p orbitals is three and, therefore, the maximum number of electrons that can be accommodated in a set of p orbitals is six.
Consequently there are six groups of p-block elements in the periodic table numbering from 13 to 18. Boron, carbon, nitrogen, oxygen, fluorine and helium head the groups. Their valence shell electronic configuration in ns2np1-6 (except for He).
The inner core of the electronic configuration may, however, differ. The difference in inner core of elements greatly influences their physical properties (such as atomic and ionic radii, ionization enthalpy, etc.) as well as chemical properties. Consequently, a lot of variation in properties of elements in a group of p-block in observed.

You must be familiar with the terms ‘LPG’ and ‘CNG’ used as fuels. LPG is the abbreviated form of Liquefied Petroleum Gas whereas CNG stands for Compressed Natural Gas. Another term ‘LNG’ (Liquefied Natural Gas) is also in news these days. This is also a fuel and is obtained by liquefaction of natural gas.
All these fuels (petrol & diesel included) contain mixture of hydrocarbons, which are sources of energy. Hydrocarbons are also used for the manufacture of polymers like polythene, polypropene, polysterene etc. Higher hydrocarbons are used as solvents for paints. They are also used as the starting materials for manufacture of many dyes and drugs.
