Options

  1. AThe sum of all the local minimum values of the twice differentiable function f: R → R defined by f (x) = x ^ 3 - 3 x ^
  2. BThe sum of all the local minimum values of the twice differentiable function f: R → R defined by f (x) = x ^ 3 - 3 x ^
  3. CThe sum of all the local minimum values of the twice differentiable function f: R → R defined by f (x) = x ^ 3 - 3 x ^
  4. DThe sum of all the local minimum values of the twice differentiable function f: R → R defined by f (x) = x ^ 3 - 3 x ^

Correct answer

B. The sum of all the local minimum values of the twice differentiable function f: R → R defined by f (x) = x ^ 3 - 3 x ^

Step-by-step solution

Generally alcohols are acidic in nature but they does not react with NaOH solution. Among the given options only phenol is acidic enough to react with NaOH solution.

So, compound 'XX' is phenol which is acidic and it is soluble in NaOHNaOH solution, but insoluble in NaHCO3{NaHCO}_{3} solution. Phenol also gives violet colour with neutral FeCl3{FeCl}_{3} solution according to the following reaction.

A compound ' X ' is acidic and it is soluble in NaOH solution, but insoluble in NaHCO _ 3 solution. Compound ' X ' also
