1 ~mol alcohol reacts with Na to give what weight of hydrogen?

Options

  1. A1 ~g
  2. B2 ~g
  3. C3 ~g
  4. D3.5 ~g

Correct answer

A. 1 ~g

Step-by-step solution

2 C ₂ H ₅ OH +2 Na 2 C ₂ H ₅ ONa + H ₂ mol mo mol 1 2 ~mol The weight of 1 2 ~mol H ₂= 2 2 ~g =1 ~g Thus, 1 ~g H ₂ is produced when 1 mole of alcohol reacts with Na.
