I,e c triple bond c

Answer 2

Hey mate!!

here's your answer...

»Acidic hydrogen are present in Alkynes, they were strongly triple bonded by carbon atoms and have hydrogen atom presented which can be removed easily by strong base Or be nutrilized.

»Additional :

»In general, acidity of hydrogen mainly depends on the atom that holds it. For acidity comparison, remove the H from the atom as H+ and then check the stability of -ve charge on the substrate (the atom which holds the H in the molecule). If the -ve charge is more stabilised then it is a good acid.[e.g M-H = M- and H+ (where M is any atom or part of a molecule)now check for the stability of -ve charge on MMore the stability of -ve charge, Better is the acid]

Electronegativity of carbon in ethyne is more.(refer to hybridisation. It is more electronegative due to greater s character than the carbon in remaining 3 molecules).hence, it can occupy the -ve charge more easily. also, more electronegativity of carbon in ethyne will polarise the C-H bond and it will be easy to remove the hydrogen.
