The correct order of electronegativity regarding the hybrid orbitals of carbon is :

Options

A. `sp lt sp^(2) gt sp^(3)`
B. `sp lt sp^(2) lt sp^(3)`
C. `sp gt sp^(2) gt sp^(3)`
D. `sp gt sp^(2) lt sp^(3)`

Answer

C

Explanation

The electronegativity of `C` is directly related to the ''s'' character of the hybrid orbital. Since `s` electrons spend relatively more time near the nuclear, the electronegativity of `C` increases with the increase of `s` character of the hybrid orbital:
? `sp (50%) gt sp^(2) (33%) gt sp^(3) (25%)`
