1. What is the systematic name?Ethyne
2. What is the molecular formula?C2H2
3. What is acetylene and why is it called a super-fuel?Acetylene is a gas with the formula C2H2. It has a strong triple bond that stores a lot of energy, so it burns very hot and is a powerful fuel.
4. How is acetylene made in factories?Factories use calcium carbide, which reacts with water to produce acetylene gas and calcium hydroxide. This is the main industrial way to make acetylene.

Electrophilic Addition: A type of chemical reaction where an electrophile adds across a double or triple bond.
Heat of Combustion: The amount of heat released when a substance is completely burned in oxygen.
Chemical Intermediate: A substance produced during a chemical process that is then used in further reactions to create the final product.
