Acidic nature of alkynes | ch#8 (Aliphatic hydrocarbans) | 12th class chemistry

#acidicnatureofalkynes #acidicnatureofacetylene In this video I have discussed about the acidic nature of alkyne in 12th class chemistry punjab text book chemistry. Acidic Nature of Alkynes In ethyne and other terminal alkynes like propyne, the hydrogen atom is bonded to the carbon atom with sp-s overlap. An sp hybrid orbital has 50% s-character in it and renders the carbon atom more electronegative than sp2 and sp3 hybridized carbons. As a result, the sp hybridized carbon atom of a terminal alkyne pulls the electrons more strongly making the attached hydrogen atom slightly acidic.
