Question | Answer |
What is Polarity? | The tendency of a molecule, or compound, to be attracted or repelled by electrical charges because of an asymmetrical arrangement of atoms around the nucleus. |
How do you determine the polarity of a molecule? | First draw the Lewis Dot Structures. Then decide if the molecules are symmetric. A molecule is non-polar if the charge distribution is symmetric and it is polar if the charge distribution is not symmetric. |
True or False: if a molecule has lone pairs it is polar. | True |
What is Electronegativity? | The tendency of an atom in a molecule to attract the electrons in a chemical bond |
True or False: Electronegativity increases when reading left to right of a periodic table. | True |
True or False: Electronegativity increases when going down the periodic table. | False |
Which has a higher Electronegativity Carbon or Oxygen? | Oxygen |
What is Delta Negative? | Delta Negative: the pull of the most electronegative atom. |
What is Delta Positive? | Delta Positive: the pull of the least electronegative atom |
True or False: if a molecule is symmetric it is polar. | False |
Which molecule is more polar Br2 or HBr? | HBr |
Which molecule is more polar H2O or H2S? | H2O |
Which molecule is more polar CCl4 or PCl3? | PCl3 |
