Question 4

what happens to the geometry of a molecule with trigonal planar geometry if it has a double bond?

Answer

the bond angles are closer to 121.9 and 116.2 degrees degrees instead of 120 degrees because the double bond contains more electron density than a single bond and therefore exerts a slightly greater repulsion on the single bonds
