This is the branch of science of dealing with the study of carbon-containing compound. Now we come to the right place where we get to the basic knowledge of organic chemistry and we are giving you all the basic MCQS of organic chemistry with Pdf Answers. We also provide you MCQS that are comes in past papers of NTS ,PPSC ,FPSC and for other jobs. Besides, this comprehensive guide would be the better option for students who participated in upcoming papers. So, we will tell you something about the background and history of organic chemistry and something about the problems and the rewards involved and something of the philosophy of what edge of the subject. You surely will not learn to everything about this content but we will be provided good knowledge. All the Pdf files cover basic and advanced knowledge of chemistry and also describe here. And read carefully. In second section you will find the series of MCQS of basic chemistry and also given online tests. This online practice test will improve your knowledge and learning skills. And also download these files with answers.

Why is organic chemistry special?
We consider some of features that make so much chemistry center on a single element, carbon. one very important is that carbon-carbon bonds are strong. so long chains or rings of carbon atom bonded to one another are possible. Diamond and graphite are two conversant example the diamond lattice being three-dimensional network of carbons atom, whereas graphite more closely look like a planar network.
The lubricating properties of graphite actually are related to its structures, which permits the planes to side one past other. We provide the basic information and history of chemistry. In this website we get knowledge about different properties and we also included the MCQS of basics chemistry.
We provide you with most important MCQS of organic chemistry that you can download free from here. In this website we facilitate the students by saving him time to find past papers MCQS.
The Breadth of Organic Chemistry:
The breadth of chemistry originally was defined as the chemistry of those materials formed by living matter and, for quite a while, there was a secure belief that it would not be possible to prepare organic compound in a laboratory out-side of a living system. Nevertheless, the designation organic is still very pertinent because the chemistry of organic compound is also the chemistry of living organisms.
Other living organism is comprised of and end-Lesly manufactures and compounds. Further all organisms consume organic compound as raw materials except for those plants that use photosynthesis or related process to synthesize their own form carbon dioxide. Modern civilization devours vast quantities of organic compounds.
Yet, many unsolved scientific problem ruins and others have not been thought of but in. in addition there are many technical and social problems to which answers seriously needed. There are many some involved problems of pollution of the environment energy, sources, bug control, drug dependance and improved exploitation of natural resources.
What is carbon and why carbon is important in chemistry?
The Carbon is a chemical element and it is represented by c and its atomic is number is 6. carbon is a non-metallic compound and have four electrons that are available to form covalent bond. Carbon belongs it to the group 14 of the chemist periodic table. This Carbon dioxide and molecules without carbon are the inorganic. Molecules with carbon are organic.
Why carbon is important?
- They are multipurpose. Can form up to four bonds (single, double, triple) in rings or in chains.
- Bonds formed are high in energy, Ex diamond
- Functional groups in organic molecules
- Are less stable then the carbon backbone but are more likely to participate in chemical reactions
- Regulate the characteristics and reactivity of organic molecules.
Chemical bond is a long-lasting attraction between molecules and ions or atoms that are enable to the formation of the chemical compound. The bonds are formed due the electrostatic force attraction between oppositely charged ions as ionic bond as through sharing electrons. This design of a bond makes it easy to draw structures of molecules.
But in order to appreciate properties and chemical reactivity of molecules we need to look at these bonds more closely. Organic chemists describe chemical bonds in organic compounds by means of theoretical models such as the valence bond (VB) or the molecular orbital (MO) models that you may have studied in general chemistry. Each has advantages and disadvantages and both are mathematically cultured.
What is Strong Chemical Bond:
These chemical bonds are the intermolecular forces that holds atom collected in the molecule. This is the chemical bond molded by the transfer of allocation of electrons between atomic Centre and release on the electrostatic force attraction between these proton’s nuclei and the electrons in the orbitals.
Theories of Chemical Bonding:
The properties of atoms include can be understood using concepts such as oxidation number and formal change. These are the electrons bond density with in a bond is not assigned to individual atoms.
Organic Chemistry Tests and Online Quiz:
Nowadays is the most critical section in the preparation of your future final papers. No one can trash the consequence the of practice quizzes and tests as they permit us to learn concepts in a better way. However, we are determined for providing you with such testing opportunities at this study platform.
So, our website concept360 is an outstanding platform that are providing you with a trustworthy and reliable stuff without any cost.
However, get the midterm examination or final term solved previous papers of different university by exploring the education category of concept360. And you can also search your selected topic and past papers MCQS with questions and answers they can be expert you in your field.
