Medicines are either man made (i.e., synthetic) or obtained from living organisms like plants, bacteria, animals, etc., and hence, the latter are called natural products. Sometimes, natural products are chemically altered by man to reduce toxicity or side effects. Write against each of the following whether they were initially obtained as a natural product or as a synthetic chemical.

Ethanol, commonly called as alcohol is an excellent solvent, is used in medicines and is an important chemical compound involved in synthesis of many chemical compounds. However, in spite of its benefits to man its impact on social behaviour has always been questioned. Media has often shown abnormal behaviour of people while drunk. It is considered as a curse in the lives of those who are addicted to alcohol. 'Alcoholic' people are not only lowering their metabolism and affecting Central Nervous System, they are also a threat to the lives of others. Anger and rude behaviour are some of its ill effects. Answer the following questions based on the above information: (i) Comment on the statement-'should production of alcohol be banned?' Give three valid reasons to justify. (ii) As a student what initiative would you take in the common concern of 'Save Life, Do Not Drink'? Give two suggestions.

Read the following passage Human body is made up of five important components, of which water is the main component. Food as well as potable water is essential for every human being. The food is obtained from plants through agriculture, Pesticides are being used extensively for a high yield in the fields. These pesticides are absorbed by the plants from the soil along with water and minerals and from the water bodies these pesticides are taken up by the aquatic animals and plants. As these chemicals are not biodegradable, they get accumulated progressively at each trophic level. The maximum concentration of these chemicals gets accumulated in our bodies and greatly affects the health of our mind and body. With regard to various food chains operating in an ecosystem, man is a:

Question Stimulus DIRECTIONS: Read the following passage carefully and complete the following sentences. When we are suddenly confronted with any terrible danger, the change of nature we undergo is equally great. In some cases fear paralyses us. Like animals we stand still, powerless to move a step in fright or to lift a hand in defence of our lives, and sometimes we are seized with panic, and again, act more like the inferior animals than rational beings. On the other hand, frequently in cases of sudden extreme peril, which cannot be escaped by flight, and must be instantly faced, even the most timid men at once as if by miracle, become possessed of the necessary courage, sharp quick apprehension, and swift decision. This is a miracle very common in nature. Man and the inferior animals alike, when confronted with almost certain death ‘gather resolution from despair’ but there can really be no trace of so debilitating a feeling in the person fighting, or prepared to fight for dear life. At such time the mind is clearer than it has ever been; the nerves are steel, there is nothing felt but a wonderful strength and daring. Looking back at certain perilous moments in my own life, I remember them with a kind of joy, not that there was any joyful excitement then; but because they brought me a new experience a new nature, as it were and lifted me for a time above himself. What is the similarity between animals and human beings?

For his 18th birthday in February Peter plants to turn a hut in the garden of his parents into a swimming pool with an artifical beach. In order to estimate the consts for heating the water and the house , peter obtains the data for the natural gas combustion and its price. Write down the chemical equations for the complete conbustion of the main components of natural gas, methane and ethane , given in table-1. Assume tht nitrogen is inert under the chosen conditions. Calculate the reaction enthalpy , the reaction entropy , and the Gibbs energy under standard conditons (1.013 xx 10^(5) Pa , 25.0^(@)C) for the combustion of methane and ethane according to the equations above assuming that all products are gaseous . The thermodynamic properties and the composition of natural gas can be found in table 1.
