Solution:

Acidic person of an animal groups is characterized based on the simplicity with which it can lose its H–iotas.

The hybridization condition of carbon in the given compound is:

As the s – character diminishes, carbon electronegativity diminishes and C – H bond pair electrons lie away from the carbon particle. Thus, H–iota to some degree positive charge increments, and H+ particles are liberated.

The s–character diminishes in the request:

sp > sp2 > sp3

Thus, the expanding request of acidic conduct is Hexane < Benzene < Ethyne.
