Question

Give reason why the ethyne is more acidic then benzene and then n-hexane?

Answer 1

Answer:

as s character increases electronegativity of carbon increased so carbon hydrogen bond become more polar n easily lose hydrogen.

Explanation:

s character in ethyne (alkyne sp carbon) is 50%

s character in benzene (sp2 carbon) is 33.3%

s character in n-hexane (alkane sp3 carbon) is 25%
