Arrange Benzene, n-hexane and Ethyne in decreasing order of acidic behaviour. Also give reason for this behaviour.

Options

  1. An-hexane > Benzene > Ethyne due to maximum s orbital character in n-hexane (50 per cent) as compared to 33 per
  2. BEthyne > n-hexane > Benzene due to maximum s orbital character in ethyne (50 per cent) as compared to 33 per c
  3. CEthyne > Benzene > n-hexane due to maximum s orbital character in ethyne (50 per cent) as compared to 33 per c
  4. DBenzene > Ethyne > n-hexane due to maximum s orbital character in benzene (50 per cent) as compared to 33 per

Correct answer

C. Ethyne > Benzene > n-hexane due to maximum s orbital character in ethyne (50 per cent) as compared to 33 per c

Step-by-step solution

Correct Option is : (C) Ethyne > Benzene > n-hexane due to maximum s orbital character in ethyne (50 per cent) as compared to 33 per cent in benzene and 25 per cent in n-hexane.
