Which do you predict to have a higher boiling point and why? 1. CH3OH 2. CH3CH₂CH₂OH Because 3. more hydrogen bonding interactions need to be overcome requiring more energy. 4. the London dispersion forces are stronger because the molecule is larger, so more energy is required to overcome them. 5. there are more covalent bonds to break, requiring more energy. 2 and 3 2 and 5 2 and 4 1 and 3 1 and 4
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.
