Question

Or Arrange benzene, hexane and ethyne in decreasing order of acidic behaviour. Also give reason for this behaviour.​

Answer 1

Answer:

I hope this is helpful

Explanation:

As the s-character increases, the electronegativity of carbon atom increases and the electrons of C-H bond pair lie closer to the carbon atom. As a result, partial positive charge of H- atom increases and H+ ions are set free. Thus, the decreasing order of acidic behaviour is Ethyne > Benzene > Hexane
