Organic Hybridization#

Illustrate the geometry and bond lengths in sp3, sp2 and sp hybridized carbons.


For each of ethane, ethylene and ethyne, build the molecule and optimize the geometry. Use the measurement tool to examine bond lengths and bond angles.


Results using the MMFF94 forcefield:

  • sp3 - ethane bond angle: 110°; C-C bond length: 1.5 Å.

  • sp2 - ethylene bond angle: 121°; C-C bond length: 1.336 Å.

  • sp - ethyne bond angle: 180°; C-C bond length: 1.200 Å.
