MCQ
Ethyl alcohol exhibits acidic character on reacting with:
  • A
    Acetic acid
  • B
    Sodium metal
  • C
    Hydrogen iodide
  • D
    Acidic potassium dichromate.
✓

Answer

  1. Sodium metal

Explanation:

CH3​CH2​−OH + Na → CH3​−CH2​−O−Na+ + $ \frac{1}{2}$ ​H2​

Acid reacts with metal to give hydrogen gas.

Hence, in above reaction CH3​CH2​OH behaves as an acid.
