Question

why ethyne is more acidic than ethene

Answer 1

Answer:

• In ethyne,the Carbon atoms are in sp hybridization state with 50% s- character. ... In this way Carbon atom i strongly attracts bond pair electrons of C-----H bond towards itself and ultimately H+ ions can be easily donated. Hence,ethyne acts as acid. Where as in ethene carbon atom exbhit SP2 hybridization.

Answer 2

In ethyne,the Carbon atoms are in sp hybridization state with 50% s- character. As the s-charater increases , electronegativity of carbon atom increases. In this way Carbon atom i strongly attracts bond pair electrons of C-----H bond towards itself and ultimately H
+
ions can be easily donated.Hence,ethyne acts as acid.Where as in ethene carbon atom exbhit SP2 hybridization.
Therefore ethyne is more acidic than ethene
