Assertion (A): The equilibrium constant ...

Assertion (A): The equilibrium constant for cyanohydrin formation is `=10^(13)` times greater for cyclo-hexanone than for cyclophentanone.
Reason (R ): For a five-membered ring, reactions are more favourable when a ring C changes from `sp^(3)` to `sp^(2)` because eclipsing interactions are removed.

A

If both (A) and (R ) true and (R ) is the correct explanation of (A).

B

If both (A) and (R ) are true but (R ) is not correct explanation of (A).

C

If (A) is true but (R ) is false.

D

If (A) is false but (R ) is true.

Consider a solution of CH_3COONH_4 which is a salt weak acid and weak base. The equilibrium involved in the solutions are : CH_3COO^(-)+H_2OhArrCH_3COOH+OH^(-) " ........"(i) NH_(4)^(+)+H_(2)hArrNH_(4)OH+H^(+)" ........"(ii) H^(+)+OH^(-)hArrH_(2)O" ........"(iii) If we add these reactions, then the net reaction is : CH_(3)COO^(-)+H_(2)^(+)+H_(2)OhArrCH_(3)COOH+NH_(4)OH" ........"(iv) Both CH_(3)COO^(-) and NH_(4)^(+) get hydrolysed independently and their hydrolysis depends on : (a) their initial concentration (b) The value of K_(h) which is (K_(w))/(K_(a)) for CH_(3)COO^(-) and (K_(w))/(K_(b)) for NH_(4)^(+) . Since both of the ions were produced form the salt, their initial concertration are same. Therefore, unless and until the value of (K_(w))/(K_(a)) or K_(a) and K_(b) is same, the degree of hydrogen of ions can't be same. To explain why we assume that degree of hydrolysis of cation and anion is same, we needed to now look at the third reaction i.e.,combination of H^(+) and OH^(-) ions. It is obvious that this reaction happens only because one reaction produced H^(+) ion and the other prodcued OH^(-) ions. We can also note that this reaction causes both the hydrolysis reaction to occur more since their product ions are being consumed. Keep this in mind that the equilibrium which has smaller value of the equilibrium constant is affected more by the common ion effect. For the same reason if for any reson a reaction is made to occur to a greater extent by the consumption of any of the prodcut ion, the reaction with the smaller value of equilibrium constant tends to get affected more. Therefore, we conclude that firstly the hydroylsis of both the ions occurs more in the presence of each other (due to consumption of the product ions) than in each other's absence. Secondly,the hydroylsis of the ion which occurs to a lesser extent (due to smaller value of K_(h)) is affected more than the one whole K_(h) is greater. Hence we can see that the degree of hydroylsis of both the ions would be close to each other when they are getting hyderolysed in the presence of each other. In the hydrolysis of salt weak acid and weak base :

Oxygen is of vital importance for all of us . Oxygen enters the body via the lungs and is transported to the tissues in our body by blood . There it can deliver energy by the oxidation of sugars. C_(6)H_(12)O_(6) + 6O_(2) rarr 6CO_(2) + 6H_(2)O This reaction releases 400 KJ of energy per mole of oxygen O_(2) uptake by blood is at four heme (Hm) group in this protein hemoglobin (Hb). Free Hm consists of an Fe^(2+) giving HmO_(2) complex. Carbon monoxides can be complexed similarily giving a Hm CO complex . CO is poison as it bonds more strongly to Hm than O_(2) does. The equilibrium constant K_(f) for the reaction: Hm+ CO hArr HCO " "........(i) is 1000 times larger than the equilibrium constant K_(2) for the reaction: Hm + CO_(2) hArr HmO_(2)" " ........(ii) Each Hb molecules can take up four molecules of O_(2) absorbs a fraction of this amount, depending on the oxygen pressure , as shown in figure1 (curve 1) . Also shown are the curve (2) and (3) for blood with two kinds of dificient Hb . These occur in patients with certain hereditary diseases. Relevant data , O_(2) pressure in lungs is 15 KPa , in the muscles it is 2KPa . The maximum flow of blood through heart and lungs is 4 xx 10^(-4)m^(-3)s^(-1) . The red cells in blood occupy 40% of the volume, inside the cells the concentration of Hb has a molar mass of 64 kg "mol"^(-1) R=8.314 J "mol"^(-1) K^(-1) , T=298k .
