Question

Which carbon is the most electronegative?

• A. $s{p}^3-$ hybridized carbon
• B. $sp-$ hybridized carbon
• C. $s{p}^2-$ hybridized carbon
• D. Always same irrespective of its hybrid state

Answer 1

The correct option is B $sp-$ hybridized carbon

We should know that s orbitals hold electrons more tightly to nucleus than p orbitals . This implies that s orbitals are effectively more electronegative and sp has more s character than ${sp}^2$. So, $sp-$ hybridized carbon is the most electronegative.
