Which of the following elements of the carbon family has the lowest boiling point?
Carbon
Silicon
Germanium
Tin
Carbon has the lowest boiling point among the elements of the carbon family.
This is because carbon has a simple molecular structure with weak van der Waals forces between the molecules, which requires less energy to break during boiling.
The force of attraction between the molecules of carbon compounds is not very strong and therefore, carbon compounds have a low melting point.
