CHM2210L Midterm UPDATED ACTUAL Exam Questions and CORRECT Answers Do all mixtures of two different organic compounds exhibit a broad melting point range? - CORRECT ANSWER- No, eutectic mixtures(minimum mp for a mixture) melt with a sharp mp range. Do organic compounds that exhibit polymorphism have different melting points? - CORRECT ANSWER- Yes, variations in the intermolecular attraction of different crystalline forms can cause polymorphs to have different but sharp mp

The most characteristic reaction if alkenes is the addition to the carbon-carbon double bond where the pi bond is replaced by two sigma bonds to two new atoms or atom groups in a reaction that occurs in multiple steps, each step has its own ___ and __. activation energy transition state what is a reactive intermediate? a high-energy species that occurs between two successive reaction steps that has the lowest energy between the two transition states three most common reactive intermed...
