Hc = ch hc=cna (4) this is not possible in any other hydrocarbon because hc = c° is highly stable

Plz explain this example briefly HC = CH HC=CNa (4) This is not possible in any other hydrocarbon because HC = C° is highly stable

    Dear Imran, let me tell you something and I want you to note it down in your notes, 'sp hybridised carbon is even more electronegative than sp3 hybridised Nitrogen and sp hybridised Nitrogen is more electronegative than sp3 hybridised Oxygen'. In acetylene, there's 50% s-character, therefore it is acidic. Rest, other hydrocarbons are not very electronegative due to low percentage of s-character! In Pauling scale, Carbon's electronegativity is around 2.5 only, which is low. Hope this helps. 😊

    Imran, accept the answer! 🙏

    Acetylene (C2H2) is acidic because it has sp hybridized carbon. Ethylene (C2H4) is not acidic as it has sp2 hybridized carbon. So C2H3- is not stable.

    Jab C2H4 nahi hai acidic to C2H6 ke bare bhul hi jao. As C2H6 has sp3 hybridized carbon.

    And you know more the % s character so more will be the eletronegativity. So more stable the negative charge
