Moderate

In hybridization, increased 's' character will make the bond length:

Correct answer: B. Shorter

  • A. Same
  • B. Shorter
  • C. None of these
  • D. Greater

Explanation

Greater the s - character, the closer the orbitals are to the nucleus and hence form stronger and shorter bonds.s −character in different hybridization states are: sp3 (25%), sp2 (33%), sp (50%)Bond length: alkanes (sp3) > alkenes (sp2) > alkynes (sp)The table presented below substantiates the claim by using actual data. It shows how alkanes have a greater bond length, followed by alkenes, and alkynes in the last place.

About Chemical Bonding

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
