The acidity of Ethyne is due to which factor?
As-character of sp hybrid orbitals
BLarge size of carbon
CElectronegativity of hydrogen
DResonance stability
✓ Correct Answer: A — s-character of sp hybrid orbitals
In sp hybridization, the high s-character (50%) makes the carbon more electronegative, allowing the H+ to be released more easily.
