Options

  1. AThe Bohr radius of a hydrogen like species is 70.53 pm. The species and the stationary state (n) are respectively
  2. BThe Bohr radius of a hydrogen like species is 70.53 pm. The species and the stationary state (n) are respectively
  3. CThe Bohr radius of a hydrogen like species is 70.53 pm. The species and the stationary state (n) are respectively
  4. DThe Bohr radius of a hydrogen like species is 70.53 pm. The species and the stationary state (n) are respectively

Correct answer

C. The Bohr radius of a hydrogen like species is 70.53 pm. The species and the stationary state (n) are respectively

Step-by-step solution

As compound, A instantly reacts with lucas reagent it should be a tertiary alcohol, and A a tertiaryl alcohol is formed by the reaction of grignard reagent, C2H5MgBr{C}_{2}{H}_{5}MgBr with C8H8O{C}_{8}{H}_{8}O,

C8H8O{C}_{8}{H}_{8}O should be a ketone and based on the formula it can be identified as a aromatic ketone.

Reaction of Grignard reagent, C _ 2 H _ 5 MgBr with C _ 8 H _ 8 O followed by hydrolysis gives compound A , which
