Why is ethanol liquid at room temperature?
Alcohol molecules can hydrogen bond to each other and to water molecules. This explains their solubility in water. At room temperature ethanol is a liquid whilst ethane is a gas. Ethanol has a higher boiling point because the attractive forces between its molecules are greater.
Why is ethanol a liquid at room temperature but does not conduct electricity?
In order for a liquid to conduct electricity, there need to be ions in the liquid that can serve to move charge (electricity) through the liquid. A solution of pure ethanol does not contain any ions and, so, will not conduct electricity.
What is the salt formed in the reaction of ethanol with sodium?
Alcohols react with sodium to form a salt (sodium alkoxide) and hydrogen gas.
Why is ethanol a liquid at room temperature whereas propane is a gas?
The obvious answer is because propane is a gas at room temperature, while 2-propanol is a liquid at room temperature. That happens because the intermolecular forces that exist between 2-propanol, or isopropyl alcohol, molecules are stronger than those that exist between propane molecules.
Why does ethanol not dissociate in water?
Because there are fewer water molecules available to make hydrogen bonds with the alcohol molecules, the alcohol becomes less soluble in the water–alcohol mixture, eventually forming a separate layer on top of the water.
Why does ethanol solution have zero conductivity?
Ethanol does not dissociate in this way; the bond between the oxygen atom and the hydrogen atom in the -OH group is much stronger. Without free ions, there is no mechanism for transporting electrical charge and the electrical conductivity is zero.
Why is ethanol a liquid while dimethyl ether is a gas?
Remember, typical room temperature is about 25 °C. That means that at room temperature, dimethyl ether is a gas, because it is above its boiling point. Ethanol, on the other hand, is a liquid at room temperature. Ethanol at that temperature is well above its freezing point but has not yet reached its boiling point.
