317087 In which of the following compounds, carbon uses \({\rm{s}}{{\rm{p}}^{\rm{3}}}\) hybrid orbitals only for bonding?

1 \(\mathrm{HCOOH}\)
2 \(\mathrm{CH}_{3} \mathrm{CHO}\)
3 \(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{COH}\)

CHXI12:ORGANIC CHEMISTRY SOME BASIC PRINCIPLES AND TECHNIQUES

317088 Assertion :
The greater the \({\text{s}}\) -character of the hybrid orbitals, greater is the electronegativity.
Reason :
The change in hybridisation is associated with the change in electronegativity.
