Why ethyne is acidic in nature in comparison to ethene and ethane?
Answers
Answer:
In a way the electronegativity of the element having more s character is more. So C in ethyne is more electronegative than in ethene and therefore Hydrogen in ethyne is more acidic than in Ethene . Ethyne contains sp hybridized carbons, while ethene and ethane contain sp2 and sp3 hybridized carbons respectively.
Answer:
In ethyne, hydrogen atoms are connected to sp hybridized carbon atoms, but in ethene, they are attached to sp2 hybridized carbon atoms and in ethane, they are attached to sp3 hybridized carbons.
Explanation:
The sp hybridized orbitals of carbon atoms in ethyne molecules have the highest electronegativity (50%) due to the highest percentage of s – character (50%): This attracts the shared pair of the C-H bond of ethyne to a greater extent than the sp2 hybridized orbitals of carbon in ethene and the sp3 hybridized orbital of carbon in ethane. In comparison to ethene and ethane, hydrogen atoms may be released as protons more easily in the ethyne molecule.
