Shapes with Three Electron Groups Trigonal Planar Arrangement

Molecular Shapes with Three Electron Groups (Trigonal Planar Arrangement) [Pg.308]

When the three electron groups are bonding groups, the molecular shape is trigonal planar (AX3). Boron trifluoride (BF3), another electron-deficient molecule, is an example. It has six electrons around the central B atom in three single bonds to F atoms. The nuclei lie in a plane, and each F—B—F angle is 120°  [Pg.308]

The nitrate ion (NO3 ) is one of several polyatomic ions with the trigonal planar shape. One of three resonance forms of the nitrate ion (Sample Problem 10.4) is [Pg.308]

The resonance hybrid has three identical bonds of bond order I5, so the ideal bond angle is observed. [Pg.308]

Effect of Double Bonds How do bond angles deviate from the ideal angles when the suiTOunding atoms and electron groups are not identical Consider formaldehyde (CH2O), a substance with many uses, including the manufacture of Formica countertops, the production of methanol, and the preservation of cadavers. Its [Pg.308]
