Front

What is the molecular shape of a molecule with three bonding pairs and no lone pairs?

Back

Trigonal planar

Front

What is the molecular shape of a molecule with two bonding pairs and no lone pairs?

Back

Linear

Front

What determines the polarity of a molecule?

Back

The difference in electronegativity between atoms and the molecular shape.

Front

What is the electronegativity value of Fluorine?

Back

4.0 (highest in the periodic table)

Front

What is the molecular shape of CF4?

Back

Tetrahedral

Front

Is CF4 a polar or non-polar molecule?

Back

Non-polar

Front

What is the effect of lone pairs on molecular shape?

Back

Lone pairs repel more strongly than bonding pairs, altering the shape.
