  Organic chemistry is the branch of chemistry that deals with the study of hydrocarbons and their derivatives. This unit consists of the shapes of carbon compounds, their structure and functional group nomenclature etc. The nature of the covalent bonding in organic compounds are described in terms of orbital hybridization concept. The three dimensional structure organic, molecules can be represented on taper by using wedge and dash formula the name of organic compound is carried all by rules that are given by IUPAC (International Union of Pure and Applied Chemistry). Compounds possessing the same molecular formula but different properties are known as Isomers and different types of isomers are explained in this unit. Organic reactions involve breaking and making covalent bonds and covalent bonds may be cleaved by heterolytic or homolytic. Substitution, addition, rearrangement and elimination reaction are the classification of organic reactions.

• Chapter 13 Hydrocarbons

  Hydrocarbon cells explain that compounds of carbon and hydrogen only. They are used for the manufacture of polymers like polyethylene, polytropon, polystyrene etc. Fuels contain a mixture of hydrocarbons which are sources of energy. Hydrocarbons are classified on the basis of carbon-carbon bonds present and they are categorised into three types (i) Saturated (alkane) (ii) Unsaturated (alkane) (iii) Aromatic. Alkanes contain carbon-carbon sigma bonds and the important reactions of alkanes are free radical substitution, combustion, oxidation and aromatization. Alkene are unsaturated hydrocarbons containing atleast one double bond. Alkenes are manufactured or prepared from alkynes, from vicinal dihalides from alcohol by acidic dehydration alkene and alkynes undergo addition reactions, which are electrophilic addition. Aromatic hydrocarbon known as ‘arenes' and most compounds found to contain benzene rings. Alkane shows conformational isomerism due to free rotation where alkene exhibits geometrical isomerism due to restricted rotation. Polynuclear hydrocarbons having fused benzene systems have carcinogenic properties. The nature of groups or substituents attached to the benzene ring is responsible for activation or deactivation of the benzene ring toward further electrophilic substitution and also orientation of the incoming group.

• Chapter 14 Environmental Chemistry

  The branch which deals with the relationship between living organisms and environment is called environmental chemistry. Due to certain undesired activities our environment is getting spoiled and the time is not so far when earth will not be able to sustain life. Atmospheric pollution is generally studied as tropospheric and stratospheric pollution whereas the troposphere is the lowest region of the atmosphere extending from earth's surface to the lower boundary of the stratosphere. It contains vapours and is greatly affected by air pollution. Stratosphere is the layer of the earth's atmosphere above the troposphere and below the mesosphere is called stratosphere. Tropospheric pollution is basically due to various oxides of sulphur, nitrogen, carbon, halogen and also due to particulate pollutants. The phenomenon in which atmosphere of earth traps - the heat coming from the sun and prevents it from escaping into outer space is called greenhouse effect and greenhouse gases warm the earth leading to the warming of air due to greenhouse gases which is called global warming.
