The term Sn is drived from 'nucleophilic substitution reaction'. 1 means unimolecular, and the rate of the reaction only depend on the concentration of one reactant; 2 means bimolecular, and the rate o...

In order to conduct electricity, charged particles must be available and these charged particles must have the possibily to move around freely. Salts consist of ions: charged particles. In the solid st...

Electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous 1- ions. Fluorine has a negative value as energy is released when the electron i...

We start by remembering the general formulas of alkenes and alkynes:
Alkenes - C_nH_2n
Alkynes - C_nH_2n-2
We calculate the molar mass of both of the...
