Question

CH4—>CH3CI—>C2H6–>CO2

Answer 1

1) CH4+Cl2= CH3Cl+HCl

2) 2CH3Cl+2Na=2NaCl+C2H6

3)2C2H6+7O2=4CO2+6H2O

Answer 2

The series of chemical reactions you've provided appears to be a representation of methane (CH4) being converted through a series of reactions into different compounds. Let's break down each step:

1. CH4 (methane) -> CH3Cl (methyl chloride) In this reaction, methane (CH4) reacts with chlorine (Cl2) in the presence of ultraviolet (UV) light to form methyl chloride (CH3Cl). The reaction is a substitution reaction, where one hydrogen atom from methane is replaced by one chlorine atom.

2. CH3Cl (methyl chloride) -> C2H6 (ethane) In this step, methyl chloride (CH3Cl) reacts with hydrogen (H2) gas in the presence of a strong base or catalyst to produce ethane (C2H6). This reaction is a reduction reaction, where a hydrogen atom is added to methyl chloride to form ethane.

3. C2H6 (ethane) -> CO2 (carbon dioxide) Finally, in this last step, ethane (C2H6) undergoes combustion, typically in the presence of oxygen (O2), to produce carbon dioxide (CO2) and water (H2O). This is an oxidation reaction, where ethane reacts with oxygen to form carbon dioxide and water.

Overall, the series of reactions represents the conversion of methane (CH4) into carbon dioxide (CO2) through the intermediate stages of methyl chloride (CH3Cl) and ethane (C2H6). It's important to note that these reactions have practical and environmental implications, as methane is a potent greenhouse gas, and its conversion to carbon dioxide contributes to global warming.
