Organic Hybridization#

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

Task#

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.

Solution#

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.
