Compound II is heated with Conc. HIHI to give a hydroxy compound A which is further heated with ZnZn dust to give compound BB. Identify AA and BB.

Compound I is heated with Conc. HI to give a hydroxy compound A which is further heated with Zn dust to give compound B

Options

  1. AThe sum of absolute maximum and absolute minimum values of the function f(x) = |2 x ^ 2 + 3x - 2| + x x in the interval
  2. BThe sum of absolute maximum and absolute minimum values of the function f(x) = |2 x ^ 2 + 3x - 2| + x x in the interval
  3. CThe sum of absolute maximum and absolute minimum values of the function f(x) = |2 x ^ 2 + 3x - 2| + x x in the interval
  4. DThe sum of absolute maximum and absolute minimum values of the function f(x) = |2 x ^ 2 + 3x - 2| + x x in the interval

Correct answer

D. The sum of absolute maximum and absolute minimum values of the function f(x) = |2 x ^ 2 + 3x - 2| + x x in the interval

Step-by-step solution

Alkyl aryl ethers are cleaved at the alkyl-oxygen bond due to the more stable aryl-oxygen bond. The reaction yields phenol and alkyl halide.

Compound I is heated with Conc. HI to give a hydroxy compound A which is further heated with Zn dust to give compound B

And then Phenol is converted to benzene on heating with zinc dust.Compound I is heated with Conc. HI to give a hydroxy compound A which is further heated with Zn dust to give compound B
