Question

(a) For the complex $\left[ Fe ( CN )_6\right]^{4-}$, write the hybridization magnetic character and spin type of the complex. [At. Number : Fe $=26$ ]
(b) Draw one of the geometrical isomers of the complex $\left.Co ( en )_2 Cl _2\right]^{+}$which is optically active.

Answer

(a) $\left[ Fe ( CN )_6\right]^{4-}$ O.N. of $Fe =x+6(-1)=-4$
$\Rightarrow x=+2$
$Fe ^{2+}=1 s^2, 2 s^2, 2 p^6, 3 s^2, 3 p^6, 3 d^6, 4 s^{\circ}$

Magnetic character: All the electrons are paired because $CN ^{-}$is a low spin ligand as a result it is diamagnetic in nature.

Read the following text carefully and answer the questions that follow:
The boiling point elevation and the freezing point depression of solutions have a number of practical applications. Ethylene glycol (CH₂OH-CH₂OH) is used in automobile radiators as an antifreeze because it lowers the freezing point of the coolant. The same substance also helps to prevent the radiator coolant from boiling away by elevating the boiling point. Ethylene glycol has a low vapour pressure. We can also use glycerol as an antifreeze. In order for boiling point elevation to occur, the solute must be non-volatile, but no such restriction applies to freezing point depression. For example, methanol (CH₃OH), a fairly volatile liquid that boils only at 65°C is sometimes used as antifreeze in automobile radiators.
i. Out of the CH₃OH and C₆H₁₂O₆, which is a better reagent for depression in freezing point but not for elevation in boiling point?
ii. Will the depression in freezing point be same or different, if 0.1 moles of sugar or 0.1 moles of glucose is dissolved in 1 L of water?
iii. 124 g each of the two reagents glycerol and glycol are added in 5 kg water of the radiators in the two cars. Which one is better for a car? Justify your answer.

iii. If the cost of glycerol, glycol and methanol are the same, then what would be the sequence of the economy to use these compounds as antifreeze?
