1.	Give reasons:a) Pure ethanoic acid is known as glacial acetic acid. b) Ethanol is used as an antifreeze in car batteries. c) Ethanol mixed with methanol is known as denaturedalcohol. d) Oxyacetylene flame is used for welding. e) Gasoline is used as a fuel in western countries.
Answer» Solution :a] Pure ethanoic acid freezes at `27^@C` during WINTER and resembles a glacier, HENCE the name glacial acetic acid. b] Ethanol when mixed with water freezes at a HIGHER temperature than water, hence it is used in radiators of cars in cold countries. c] Methanol is poisonous, hence when mixed with ethanol, it makes the latter unfit for consumption. d] Oxyacetylene gives out a large amount of HEAT when burnt. e] Alcohol added to PETROL increases the efficiency of the fuel.
