Ozone layer acts as one of the most important life support system. The major cause of ozone layer destruction is believed to be the release of chlorofluorocarbon compounds. UV radiation causes the chlorofluouocarbons to dissociate : CF_(2) Cl overset(hv)(rarr) Cl* +CF_(2) CI A highly reactive chlorine atomis responsible for the decomposition of ozone. Cl* + O_(3) (g) rarr ClO* + O_(2) (g) ClO* + O(g) rarr Cl* + O_(2) (g) Free radicals of chlorine decompose ozone molecules in a chain reaction. The depletion of ozone layer leading to ozone hole has, however, been mainly observed in the stratosphere over Antarctica. Special type of cloud called polar stratospheric colouds are formed over Antarctica.These clouds (contain solid HNO_(3).3H_(2)O ) play an important role in ozone depletion. ClO* + NO_(2) rarr ClONO_(2) ClONO_(2) + H_(2) O rarr HOCl + HNO_(3) ClONO_(2) + HCl rarr Cl_(2) + HNO_(3) HOCl overset(hv)(rarr) HO* + Cl* The reactive chlorine atoms thus formed are rendered to deplete ozone layer. Peeling of ozone umbrella, which protects us from UV rays is caused by:

(iii) The main polluting components of smog are oxides of carbon. (iv) The presence of carbon monoide in air leads to the formation of ozone in smog.

Which of the following statements regarding biodiversity hot spots are incorrect? i) High endemism ii) High levels of species richness iii) Total number is 34 in the world iv) Five of these occur in India v) High alien species invasions vi) Cover less than 2% of the earth's land area, but if properly conserved, they can reduce extinctions by about 30%

Structural isomers have different covalent linkage of atoms. Stereoisomers are compounds that have same sequence of covalent bonds but differ in the relative dispositions of their atoms in space. Geometri cal and optical isomers are the two important types of configurational isomers. The compound with double bonds or ring structure have restricted rotation, so exist in two geometrical forms. The double bonds in larger rings (ring size 10 carbon large) can also cause geometrical isomerism. The optical isomers rotate the plane of plane-polarised light. A sp^(3) -hybridised carbon atom bearing four different types of substituents is called an asymmetric centre or chiral centre. A chiral object or molecule cannot be superimposed on its mirror image. Stereoisomers that are mirror images of each other are called enantiomers. The stereosomers that the pot mirror images of each other are called diastereomers. Diasteremers have different physical properties. A racemic mixture is optically inactive and contains equal amounts of both the enantiomers. Resolution refers to method of separating a racemic mixture. Into two pure enantiomers. A meso compound is an optically inactive stereoisomer, which is achiral due to the presence of an internal plane of symmetry or centre of symmetry within the molecule. The number of chiral centres present in the following compounds is
