Question

which of the following should have the highest surface tension at a given temperature? group of answer choices carbon tetrachloride methane carbon tetrafluoride carbon tetrabromide carbon tetraiodide

Answer 1

Carbon tetrabromide (CBr4) should have the highest surface tension at a given temperature due to its strong intermolecular forces.

Step-by-step explanation:

Surface tension is a property that depends on the intermolecular forces between molecules in a liquid. The stronger the intermolecular forces, the higher the surface tension. Among the given options, carbon tetrabromide (CBr4) should have the highest surface tension at a given temperature because it has the strongest intermolecular forces due to its larger number of halogen atoms. The other compounds in the group, carbon tetrachloride (CCl4), methane (CH4), carbon tetrafluoride (CF4), and carbon tetraiodide (CI4), have weaker intermolecular forces and therefore lower surface tensions.

Answer 2

Carbon tetrachloride should have the highest surface tension at a given temperature

Step-by-step explanation:

Surface tension is the energy required to increase the surface area of a liquid by a specific amount. The stronger the intermolecular forces, the higher the surface tension. Carbon tetrachloride (CCl4) would have the highest surface tension at a given temperature because it has strong intermolecular forces due to its polarity and the presence of chlorine atoms which can form dipole-dipole interactions.
