sp-hybrid : closer to nucleus : : shorter and stronger bond length : ?

Hybridisation influences the bond length and bond enthalpy (strength) in organic compounds. The sp-hybrid orbital contains more s-character and hence it is closer to its nucleus and forms shorter and stronger bond than sp3 -hybrid orbital. The change in hybridisation affects the electronegativity of carbon. The greater the s-character of the hybrid orbitals, the greater is the electronegativity.
