Which of the following statements best explain the greater acidity of terminal alkynes (RC-=CH) compared with monosubstituted alkenes (RCH=CH_(2))?

Answer»

The sp-hybridized carbon atoms of the alkynes are LESS ELECTRONEGATIVE than the `sp^(2)` CARBONS of the alkene.
The TWO `pi` bonds of the alkyne are better able to STABILIZE th negative charge of the anion by resonance.
The sp-hybridized carbons of the alkyne are more electronegative than the `sp^2` carbon of the alkene.
The question is incorrect-alkenes are more acidic than alkynes.
