Acetylene (ethyne) is widely used in oxy-acetylene welding because its combustion in oxygen produces an extremely high flame temperature, often exceeding 3000 degrees Celsius. This intense heat is sufficient to melt most metals, making it ideal for welding and cutting applications. The high energy density of the triple bond in acetylene contributes to this high heat output.

What is the difference in molecular mass units between methyl alcohol and ethyl alcohol?
Methyl alcohol is CH3OH and ethyl alcohol is C2H5OH. The difference between these two consecutive members of the alcohol homologous series is a CH2 group. The molecular mass of a CH2 unit is 12 (for Carbon) + 2 (for Hydrogen) = 14 atomic mass units.
3283
What type of alcohol, when oxidized, produces an aldehyde with the same number of carbon atoms?
Primary alcohols have a hydroxyl group (-OH) attached to a carbon atom that is only bonded to one other carbon. Oxidation of primary alcohols yields aldehydes. Secondary alcohols, on the other hand, are oxidized to ketones.
3284
Which of the following types of alcohols cannot be oxidized?
Tertiary alcohols lack a hydrogen atom directly attached to the carbon bearing the hydroxyl group. This makes them resistant to oxidation, which requires the removal of hydrogen. Primary and secondary alcohols can be oxidized to aldehydes and ketones, respectively.
Acetophenone is a type of organic compound that contains a carbonyl group (C=O) attached to a carbon atom, which is characteristic of ketones. This classification is based on the functional group present in the molecule, making it a ketone.

What substance is produced when isopropyl alcohol undergoes oxidation?
Oxidation of alcohols typically results in the formation of aldehydes or ketones. Isopropyl alcohol, upon oxidation, specifically forms the ketone, propanone (also known as acetone).
