CBr4 would have a VSEPR shape that is tetrahedral, and since the difference between carbon and bromine electronegativity values are 0.3 (2.8(br)-2.5(c)), the molecule is non-polar. Therefore, the only IMFs that would be present in a non-polar molecule are
london dispersion forces
.

What is the IMF of CBr4?
CBr4 would have a VSEPR shape that is tetrahedral, and since the difference between carbon and bromine electronegativity values are 0.3 (2.8(br)-2.5(c)), the molecule is non-polar. Therefore, the only IMFs that would be present in a non-polar molecule are
london dispersion forces
.
Is CBr4 dipole-dipole?
So, Is CBr4 Polar or Nonpolar? CBr4 (Carbon tetrabromide) is nonpolar in nature because of the symmetrical arrangement of four bromine atoms around carbon. As a result, the dipoles of the C-Br bond
get canceled by each other
resulting in CBr4 a nonpolar molecule.
Does CBr4 have stronger intermolecular forces?
FalseFalse: C B r 4 has weaker intermolecular forces than C C l 4 .: CBr4 has
weaker
intermolecular forces than CCl4. FalseFalse: C B r 4 has a higher vapor pressure at the same temperature than C C l 4 .: CBr4 has a higher vapor pressure at the same temperature than CCl4.
Which compound has the strongest intermolecular forces?
HF
(boiling point = 19.4 degrees Celsius) has the strongest intermolecular forces.
Is NH3 a hydrogen bond?
NH3 can form hydrogen bonds
. This is because hydrogen bonds can be formed when hydrogen is covalently bonded to a highly electronegative atom like…
What is the strongest intermolecular force in methane?
Therefore the strongest intermolecular forces between CH4 molecules are
Van der Waals forces
. Hydrogen bond are stronger than Van der Waals forces therefore both NH3 and H2O will have higher boiling points than CH4.
Which type of intermolecular attractive force is the strongest?
- The Ion-dipole force is the strongest imf.
- Occurs when a polar molecule (molecule with a dipole) comes in contact with an ion.
- This is why some ionic compounds will dissolve in water.
- Draw a picture below:
Which substance has the weakest intermolecular forces?
- Oil- Only London Dispersion Forces (the weakest intermolecular force)
- Water- London Dispersion, Dipole-Dipole, and Hydrogen Bonding.
Is MgBr2 dipole-dipole?
No
, like nearly all magnesium compounds, MgBr2 (magnesium bromide) is ionic.
Is OF2 dipole-dipole?
OF2 is a polar molecule, so will have both
dipole-dipole interactions
and dispersion forces.
Is CO2 dipole-dipole or dispersion?
Carbon dioxide does not have dipole-dipole forces
due to symmetry of the dipoles found in the molecule as a result of the polar bonds. Carbon dioxide is not a polar molecule despite its polar bonds. Carbon dioxide also does not have hydrogen bond forces because it is a nonpolar molecule.
What is the force that holds ethanol together?
The especially strong intermolecular forces in ethanol are a result of a special class of dipole-dipole forces called
hydrogen bonds
.
Why SiCl4 is more volatile than CCl4?
The C-Cl bond in
CCl4 is more polar
and hence results in tighter holding of the molecules and stronger intermolecular forces . Where as in SiCl4 the electronegativity difference is less and hence intermolecular forces are weaker results in low boiling point .
Is CBr4 more polar than CCl4?
C)CCl4 because
polar forces between its molecules are greater than
in CBr4 .
