Identify the correct statements from the following i. Reaction of hydrogen with fluorine occurs even in dark. ii. Manufacture of ammonia by Haber process is an endothermic reaction iii. HF is electron rich hydride

Options

  1. Ai, iii only
  2. Bi, ii, iii
  3. Cii, iii only
  4. Di, ii only

Correct answer

A. i, iii only

Step-by-step solution

H ₂( ~g )+ F ₂( ~g ) 2 HF ( g ) F ₂ is highly reactive so it reacts with hydrogen even in dark. N ₂+3 H ₂ [200 ~atm ] Fe (Catalyst ) 400-450^ C 2 NH ₃+ Heat The reaction is an exothermic reaction, there is a release of energy. HF is electron rich hydride because its fluorine atom having extra electrons present as lone pair. So any (i) and (iii) are correct.
