• It is a colourless, dense, oily liquid having specific gravity 1.84 at 298 K. 
• It has freezing point 283 K and boiling point 611 K. 
• It is a strong dehydrating agent and dissolves in water with the evolution of a large amount of heat. 
• It is a strong dibasic acid and acts as an oxidising agent.

Correct Answer is: (b) KCl > NaCl > LiCl 

The correct order is KCl > NaCl > LiCl .in case of Alkali metals, hydration energy decreases with increase atomic number e.g., order of hydration energy is Li⁺ > Na⁺ > K⁺ > Rb⁺ > Cs⁺. Now, equivalent conductance is directly proportional to mobility

(i) This is a compound bar graph showing the contribution of primary, secondary and tertiary sectors to the national income of India and Brazil.

(ii) It also shows the percentage of population engaged in these sectors.

(iii) The contribution of primary, secondary and tertiary sector to India’s national income is about 17%, 26% and 57% respectively.

(iv) Whereas the contribution of primary, secondary and tertiary sector to Brazil’s national income is about 5%, 28% and 67% respectively.

(v) The population engaged in primary, secondary and tertiary sector of India is about 49% 24% and 27% respectively.

(vi) The population engaged in primary, secondary and tertiary sector of Brazil is about 10%, 19% and 71% respectively.

(vii) Thus it is understood clearly from the graph that Brazil is not an agrarian economy like India.
