How is it that the dipole moment of HCl (1.08 D) is larger than the dipole moment of HBr (0.82 D), yet HBr boils at a higher temperature? Choose one: A. Both dipole-dipole interactions and dispersion forces need to be considered. B. More information is needed. C. HBr is capable of hydrogen bonding while HCl is only capable of dipole-dipole interactions. D. The dipole-dipole interaction is weaker than the dispersion forces. E. The dipole moment is irrelevant to the boiling point. F. HBr is ionic, HCl is not. G. This is simply an exception to the rule that the stronger dipole has the stronger dipole-dipole interactio
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
