Let’s give the names of organic substances.
C8H18 – octane; C9H20-nonane; С10Н22 – dean. Formulas of organic substances correspond to the total СnH2n + 2, which corresponds to the class of alkanes. Make equations:
substitution reaction C8H18 + CL2 = C8H17CL + HCL;
combustion reaction C9H20 + 14O2 = 9CO2 + 10CO2;
thermal cracking at 1000 degrees C10H22 = 10C + 11H2
C19H38 – the formula corresponds to the general CnH2n, a class of alkenes. Here is an example of an addition reaction:
C19H38 + H2 = C19H40
