24. The shape of $\mathrm { XeO } _ { 2 } \mathrm {~F} _ { 2 }$ molecule is (A) trigonal bipyramidal (B) square planar (C) tetrahedral (D) see-saw
ANSWER : D
For a dilute solution containing 2.5 g of a non-volatile non-electrolyte solute in 100 g of water, the elevation in boiling point at 1 atm pressure is $2 ^ { \circ } \mathrm { C }$. Assuming concentration of solute is much lower than the concentration of solvent, the vapour pressure ( mm of Hg ) of the solution is (take $K _ { \mathrm { b } } = 0.76 \mathrm {~K} \mathrm {~kg} \mathrm {~mol} ^ { - 1 }$ ) (A) 724 (B) 740 (C) 736 (D) 718
