Arrange the following compounds in decreasing order of acidity from left to right, and explain the reason in less than 90 words.
1 answer:
Explanation:
More is the electronegativity of atoms attached to the alpha carbon atom more will be the attraction of electron towards it. As a result, release of hydrogen ion will be easier.
Therefore, there will be increased in acidity of the compound.
Since, fluorine, chlorine and bromine are all group 17 elements and fluorine is more reactive than chlorine. On the other hand, chlorine is more reactive than bromine.
Hence, ability to attract the electrons towards itself will be maximum in fluorine and least in bromine.
Therefore, decreasing order of acidity of the given compounds is as follows.

Answer : The value of equilibrium constant (K) is, 424.3
Explanation : Given,
Concentration of at equilibrium = 0.067 mol
Concentration of at equilibrium = 0.021 mol
Concentration of at equilibrium = 0.040 mol
The given chemical reaction is:
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
Thus, the value of equilibrium constant (K) is, 424.3
