Carbon-Carbon double bond length in C3H6 is:

Correct answer: C. 133 pm

  • A. 154 pm
  • B. 120 pm
  • C. 133 pm
  • D. 105 pm

Explanation

The carbon-carbon double bond length in C3H6 is 133 pm. This is shorter than the carbon-carbon single bond length in ethane (C2H6), which is 154 pm. This is because the double bond is shorter because the electrons in the double bond are shared between the two carbon atoms, which brings the nuclei of the two atoms closer together.

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.
