What happens to ethanol at C?
At 78.37°C, ethanol boils and undergoes a phase change from liquid to gas. It turns into ethanol vapor, which can be collected and condensed back into liquid ethanol through condensation.
What is the SN1 reaction that produces ethanol from chloroethane?
In an SN1 reaction, chloroethane undergoes nucleophilic substitution to form ethanol. The chloroethane molecule first undergoes heterolytic cleavage to form a carbocation intermediate. Then, a nucleophile such as water attacks the carbocation, resulting in the formation of ethanol as the final product.
What element sublimes when gently heated?
Iodine is an element that sublimes when gently heated. Sublimation is the process of a substance transitioning directly from a solid to a gas phase without passing through the liquid phase.
What happens when ethanol is treated with PCl5?
When ethanol is treated with PCl5, it undergoes a substitution reaction where the hydroxyl group (-OH) of ethanol is replaced by a chlorine atom. This results in the formation of ethyl chloride and phosphorous oxychloride as byproduct.
What is the energy source of ethanol?
The energy source of ethanol is renewable plant material, such as corn, sugar cane, or cellulose from wood or grasses. This plant material undergoes fermentation to produce ethanol, which can be used as a fuel source.

What elements will be present in the substances that are created when ethanol burns?
The products of burning ethanol are carbon dioxide (CO2) and water (H2O). When ethanol undergoes combustion, it reacts with oxygen to produce these two substances along with heat and light energy.
What is the balanced equation when ethanol undergoes complete combustion?
Ethanol + Oxygen --Δ--> Carbon dioxide + WaterC2H5OH + 3 O2 --Δ--> 2 CO2 + 3H2O
What yellow solid heated in no air turns black?
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
What happens when ethanol is heated in presence of concentrated H2SO4?
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
Does ethanol sublime?
No. Only solids sublime, as sublime means to go from a solid directly to a gas. Ethanol evaporates.
What state is the iodine in when it is heated?
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
What reactants produce carbon dioxide?
When an organic molecule such as methane or ethanol undergoes complete combustion (in the presence of oxygen) it produces Carbon dioxide and water.
