Which of the following is a hazard associated with 2-methyl-2-butanol?

2-methyl-2-butanol is primarily classified as a flammable substance. This means that it can catch fire and burn easily in the presence of an ignition source. Its structure allows it to be volatile at room temperature, which contributes to its flammability. When considering safety protocols in the laboratory, understanding the flammability of organic solvents like 2-methyl-2-butanol is crucial for ensuring proper handling, storage, and usage.

While the term "oxidizing agent" is used in chemistry to describe a substance that can accept electrons and bring about oxidation in another substance, 2-methyl-2-butanol does not exhibit this property. Instead, it functions more as a conventional alcohol and is mainly involved in reactions typical of alcohols, rather than acting as an oxidizer. Hence, classifying it as an oxidizing agent does not align with its chemical behavior and properties.

Additionally, while "combustible" is a term that implies a substance can ignite and burn, the more specific classification of "flammable" is more appropriate and indicates a higher degree of risk. Explosive refers to substances that can rapidly expand and release energy, which does not accurately characterize 2-methyl-2-butan
