All the others are weak acids. A strong acid is one that dissociates completely when it dissolves in water. Dissociate means that the substance splits apart into ions. There are only a few strong acids in water, they are: HBr, HCl, HI, HNO3, HClO4 and H2SO4 (for the first H only) All other acids are weak acids. Chemists use the term strong or weak with regard to acids and bases to tell how much the substance dissociates in water.
The London dispersion forces are however very weak and will most likely not last long. Hydrogen bondings can be simplified and said to be a strong version of a dipole-dipole bonding which occurs when the positively charges side of a molecule consists of Hydrogen and it binds to one of the three most electronegative elements (Nitrogen, Oxygen and Flourine.)
