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

Hybridization 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 hybridization affects the electronegativity of carbon. The greater the s-character of the hybrid orbitals, the greater is the electronegativity.
