Chemical Properties and Interchange Between Homologous Series (3)

Step to balance the equation for combustion (3)

Step 3: Balance O and you can use fractions

The main component of natural gas

Is methane, CH4

Produced when organic waste decomposes in the absence of oxygen, O2

Methane gas, CH4

Chemical properties of alkanes in terms of substitution reactions (1)

Alkanes undergo substitution reaction with halogens such as chlorine, Cl2 and bromine, Br2 under sunlight or ultraviolet (UV) rays

Chemical properties of alkanes in terms of substitution reactions (2)

Substitution reaction occurs when each hydrogen atom, H in an alkane molecule is substituted one by one with halogen atoms, until all the hydrogen atoms, H have been substituted.

Chemical properties of alkanes in terms of substitution reactions (3)

Sunlight or UV rays are needed to break the covalent bonds in the halogen molecules, such as chlorine, Cl2 to produce chlorine atoms, C

Examples of alkane substitution reactions

When methane gas, CH4 reacts with chlorine gas, Cl2 under sunlight, various molecules are formed due to the substitution reaction

Chemical properties of alkene (1)

Alkenes are chemically more reactive than alkanes due to the existence of a double covalent bond between two carbon atoms, C

Chemical properties of alkene (2)

Almost all chemical reactions in alkenes occur at the double bond
