List in tabular form three physical and two chemical properties on the basis of which ethanol and ethanoic acid can be differentiation.

The difference between Ethanol and Ethanoic acid are as follows:




























Ethanol



Ethanoic acid



(i) Ethanol is neutral in nature. It is neither acidic nor basic and doesn’t have any effect on litmus paper.



(i) Ethanoic acid is acidic in nature and turns blue litmus red.



(ii) Ethanol has a burning taste and has very low melting point as well as low boiling point. The melting point of the Ethanol is 156 K and boiling point is 351 K.



(ii) Ethanoic acid is sour in taste and is having a moderate melting (290 K) and boiling point (391 K).



(iii) It has very low melting point (156 K)and low boiling point (351 K).



(iii) It has moderate melting point


and boiling point



(iv)Ethanol reacts with sodium (Na) metal vigorously. The product formed is sodium Ethoxide and H2 gas is evolved which burns with a pop sound. The chemical reaction involved is as follows:


2C2H50H + Na 2C2H50Na + H2



(i) Ethanoic acid reacts with carbonates to form salt (sodium ethanoate) and releases CO2 gas:


2CH3COOH + Na2CO3 2CH3COONa+ co2+ H2



(ii) On warming Ethanol with ethanoic acid and a few drops of concentrated H2SO4, a sweet smelling ester will be formed. This reaction is known as Esterification. The chemical equation will be as follows:


C2H5OH+CH3COOHCH3COOC2H5 + H2O



(ii) On warming Ethanol with ethanoic acid and a few drops of concentrated H2SO4, a sweet smelling ester will be formed. This reaction is known as Esterification. The chemical equation will be as follows:


C2H5OH + CH3COOHCH3COOC2H5 + H2O

State the law of refraction of light that defines the refractive index of a medium with respect to the other. Express it mathematically. How is refractive index of any medium 'A' with respect to a medium 'B' related to the speed of propagation of light in two media A and B? State the name of this constant when one medium is vacuum or air. The refractive indices of glass and water with respect to vacuum are 3f1.and 4/3 respectively. If the speed of light in glass is 2108 m/s, find the speed of light in (i)vacuum, (ii) water.
