Question

Some non-polar substances can be liquid at room temperature, its explanation is given by which of the following?

• A. The molecules form bonds by sharing electrons
• B. Temporary dipoles with partial charges are formed by the molecules
  
• C. The molecules form ions with opposite charges by transferring electrons
• D. The molecules form positive ions that are held together by free electrons
• E. The molecules form temporary bonds between hydrogen and electronegative atoms

Answer 1

The correct option is B Temporary dipoles with partial charges are formed by the molecules

Some non-polar substances can be liquids at room temperature, its explanation is given by the statement (B).
Temporary dipoles with partial charges are formed by the molecules.
The intermolecular forces of attraction are developed between these temporary dipole molecules which results in the liquid state of the substances.
