    order of stability 1>2>3 from going 1 to 3 electronegativity increases as s character increases which decreases the stability of carbocation

    More is the s character, more is the electronegativity i.e more is the -I effect. As stability of carbocation is directly proportional to +I effect and inversely to -I effect. Ist ine is sp3 hybridized i.e 25% s character... 2nd one is sp2 hybridized i.e 33.33% s character..3rd one sp hybridized i.e 50% s character. Hence -I effect increases in the order of 1<2<3 and so stability decreases in the order 1>2>3.

    how s character tells electronegativity ?

    eduncle-logo-app

    Hybrid orbitals having more s character are more electronegative because s orbital is nearer to the nucleus and hence more attracted by the nucleus. ... Hence attraction of electron in a bond towards the nucleus decreases in the order sp>sp2>sp3. Hence electronegativity decreases in above order.

    more the EN, more is the -I. more the s characters more will be the EN so more will be the -I or less will be the +I now we know that stability of carbocation is directly proportional to +I so order will be I>II>III
