ACETYLENE HAS AN ACIDIC NATURE. IT MEANS AN ACIDIC TENDENCY OR IT CAN LOOSE PROTON IF PROVIDED A SUITABLE REAGENT (HIGHLY BASIC) . IT IS NOT A STRONG ACID TO REACT WITH WEAK BASE LIKE NA2CO3. EVEN NAOH OR KOH ALSO DOES NOT REACT. ONLY BASE LIKE NAOH2 (SODAMIDE) OR TOLLENS REAGENT AND A FEW OTHER ARE ABLE TO REPLACE H+ OF ACETYLENE BY THE METAL ATOM.
IN ACETYLENE CARBON IS SP HYBRIDISED. THE BOND LENGTH SP <SP2 <SP3. SO SP BOND IS SMALLEST THE BONDED PAIR IN CASE OF SP HYBRIDISED BOND IS NEARER TO C THAN IN CASE OF SP2 AND SPA BONDS. SO HYBRIDISED CARBON IS MORE ELECTRONEGATIVE AND CAN PULL ELECTRON MORE NEARER TO THE CARBON AND MAKE HYDROCARBON ACETYLENE ACQUIRE A LITTLE POSITIVE CHARGE. THUS THE HYDROGEN BECOME A LITTLE ACIDIC IN NATURE BUT NOT LIKE HYDROGEN OF AN REGULAR ACID LIKE CH3COOH AND EVEN MUCH LESS THAN C2H5OH.
