Question

Which of the following does not occur at the boiling point of an organic compound? The atmospheric pressure decreases The temperature of the liquid can not increase any further The vapor pressure of the liquid equals the atmosphere pressure The gas of the compound also condenses Decreasing the atmospheric pressure decreases the boiling point of a compound. True False You have measured the melting point of a solid, and found the range to be 45 - 47 degrees C. What is the most likely identity of this material? lauric acid impure benzophenone stearic acid naphthalene

Explanation / Answer

Question 1) The atmosphere pressure decreases.This doen't happen. The boiling point of a substance is the temperature at which the vapor pressure is equal to atmosphere pressure.

Question 2) True.

An increase in atmospheric pressure increases the boiling point of a liquid. Conversely, a decrease in atmospheric pressure decreases the boiling point of a liquid.

Question 3) Impure Benzophenone has melting point in the range of 45-47 degrees C
