Chair and Boat Bond Angles

Postby Lauren Hekman 1A » Thu Mar 10, 2016 11:22 am

Are the bond angles for chair and boat conformations both 109 degrees?

Chair is 109
Boat is not 109. There is some slight angle strain.

No, 109 degrees is the ideal bond angle for the sp3 hybridized carbons and so when the cyclohexane adopts different conformations in order to become more stable, the bond angles get closer to the ideal so when it is in the chair conformation, the bond angles are roughly 110.9 degrees.

How do we figure out the c-c-c angles? Are we just expected to memorize them?
