Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the shape of a molecule with two bonding pairs and one lone pair of electrons?

Back

Bent

Front

How can you determine if a molecule is polar or non-polar?

Back

By examining the symmetry of the molecule and the electronegativity differences between atoms.

Front

What is the molecular geometry of SiS2?

Back

Linear

Front

In a polar molecule, where is the partial positive charge typically located?

Back

On the less electronegative atom.

Front

What is the effect of lone pairs on molecular shape?

Back

Lone pairs repel more strongly than bonding pairs, affecting the overall shape.

Front

How many unshared pairs of electrons can a bent molecule have?

Back

1 or 2

Front

What is the molecular geometry of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral

Front

What is the significance of electronegativity in determining molecular polarity?

Back

Electronegativity differences between atoms create dipoles, leading to polarity.

Front

What is the shape of a molecule with three bonding pairs and one lone pair?

Back

Trigonal pyramidal
