Is ClF4- polar or non polar?
There are two allowed structures of SF4Cl2... the cisform where one chlorine is in an equitorial position and one is axial, and the trans form where both chlorines are in axial positions. In the trans form the S-F bond dipoles all cancel each other, as do the S-Cl bond dipoles, because they are opposite each other. Therefore the molecule is non-polar. In the cisform, two of the S-F bond dipoles cancel, but because the other S-F bond dipoles are across from S-Cl bond dipoles, they do not cancel (S-F is more polar than an S-Cl bond). Therefore, the cisform is polar.
How does dipole moment help us to predict geometry of molecules?
The dipole moment tells us that there is net dipole on the molecule which indicates that any dipoles due to polarity of the covalent bonds do not cancel each other out. For example H2O has a dipole moment which rules out a linear structure where the bond dipoles would cancel each other out.
What is the strongest intermolecular attraction that must be broken in ethane?
The strongest intermolecular attraction in ethane is London dispersion forces. These forces are caused by temporary fluctuations in electron distribution, leading to temporary dipoles in neighboring molecules.
Any molecule that has a polar geometry is called what?
A molecule with a polar geometry is called a polar molecule. Polar molecules have an uneven distribution of electron density, resulting in a separation of electric charge and the presence of a positive and negative pole within the molecule.
What molecule is a polar bond but is not a polar molecule?
Carbon dioxide (CO2) is a molecule with polar bonds (between carbon and oxygen), but it is a nonpolar molecule overall because the polar bonds are oriented in a way that cancels out their dipoles.
