1. The bum in oxygen to form water and carbon (iv) oxide CH4(g) + 2O2(g) → CO2(g) + 2H2O(L) 2. They are undergo substitution reaction with chlorine in presence of ultraviolet light CH4(g) + CL2(g) → CH2CL2(g) + HCL(g) CH2CL2(g) + CL2(g) → CH2CL2(g) + HCL(g) CH2CL2(g) + CL2(g) → CHCL3(L) + HCL(g) CHCL3(L) + CL2(g) → …
1. It is neutral to litmus paper. 2. It is slightly soluble in water 3. It is a colourless and odorless gas 4. It is less dense than air
METHANE (CH4) is the simplest compound in the alkane series. It is prepared laboratorilly by heating anhydrous sodium ethanoate with an alkali, usually soda–lime. CH3COONa(s) + NaOH → Na2CO2(s) + CH4(g)
ALKANE: These are saturated hydrocarbons with molecular formulae of CnH2n + 2. They are least reactive since they are saturated the members are methane ethane, propane, butane, pentane and hexane etc.
They have the same molecular formula They have the same chemical properties They differ from each successive member by CH2 They show regular grading in their physical property. They are produced by the same method. NB: Functional group is atom or group of atoms, which determine chemical reactions, or properties of a homologous series.
It is a family of organic compounds, which shows regular grading of properties but differ from each successive member by Ch2 or mass of 14.
