Molecular Shapes

Front

What is the parent geometry for a molecule with 3 electron groups?

Back

Trigonal Planar

Front

Is a molecule with symmetrical polar bonds always nonpolar?

Back

Yes, if the molecular geometry is symmetrical, the molecule is nonpolar.

Front

If a molecule has polar bonds, does it mean the molecule is polar?

Back

False, a molecule can have polar bonds and still be nonpolar if the geometry is symmetrical.

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the parent geometry for a molecule with 5 electron groups?

Back

Trigonal Bipyramidal

Front

What is the bond angle in a trigonal planar geometry?

Back

120 degrees

Front

What is the bond angle in a tetrahedral geometry?

Back

109.5 degrees

Front

What is the molecular shape of a molecule with 4 electron groups and 1 lone pair?

Back

Trigonal Pyramidal

Front

What is the molecular shape of a molecule with 2 electron groups and 2 lone pairs?

Back

Bent

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, altering the bond angles.
