Complete the following. 2 C 2 H 6 + 7 O 2 → ____ + _____ + Heat

Combustion is a chemical change in which the combustible substance reacts with oxygen present in the air to give heat energy and light energy. Ethane with the chemical formula C 2 H 6 on combustion produces carbon dioxide, water, heat, and light. The balanced chemical equation for the combustion of ethane is given below: 2 C 2 H 6 + 7 O 2 → 4 CO 2 + 6 H 2 O + Heat + Light

Complete the following series of reactions. C 2 H 5 OH → 170 o C Conc . H 2 SO 4 _____ → Cl 2 _____

Dehydration is a process in which the water molecule is removed from a compound. Ethanol with the formula C 2 H 5 OH can be converted into ethene by dehydration with concentrated sulphuric acid. Concentrated sulphuric acid acts as the dehydrating agent in this reaction as it removes one water molecule from ethanol. Thus, the first reaction is a dehydration reaction. Alkenes are unsaturated hydrocarbons with double bonds. Unsaturated compounds generally undergo addition reactions, such as the addition of chlorine. Effectively addition reaction removes the multiple bonds by the addition of atoms or groups of atoms. Ethene undergoes the addition of chlorine to give 1 , 2 -dichloroethane as the final product. The complete reaction is given below: C 2 H 5 OH Ethanol → 170 o C Conc . H 2 SO 4 C 2 H 4 Ethene → Cl 2 H 2 C Cl - C ( Cl ) H 2 1 , 2 - dichloroethane

Complete the following series of reactions: C 2 H 4 + H 2 O → _____ → 160 o C Excess H 2 SO 4 _____

Ethene with the chemical formula C 2 H 4 on hydrolysis with water gives ethanol as the product. The water molecule attacked the double bond to give the corresponding alcohol. The resulted ethanol on dehydration with concentrated sulphuric acid gives back the ethene. C 2 H 4 Ethene + H 2 O Water → C 2 H 5 OH Ethanol → 160 o C Excess H 2 SO 4 C 2 H 4 Ethene

What is the special feature of the structure of ethyne?

Ethyne with the chemical formula C 2 H 2 is the first member of the alkyne series. Ethyne with a triple bond is an unsaturated simple alkyne with a linear structure, where two hydrogen atoms are bonded to each carbon atoms and the carbon atoms are bonded to each other with the triple bond. The structural formula of ethyne is given below.
