Choose the molecules containing an IR stretching frequency of 3500-3000 cm-1.
Correct Answer: D.All of them
The range 3500-3000 cm-1 is typically associated with stretches between heteroatoms and a hydrogen atom, for example NH and OH bonds. They may appear broad, intense and jagged (COOH), broad and smooth (OH) or less intense and sharper (NH). The preceding sentence is likely more than you would need to know for the MCAT. In general, for MCAT purposes, it is useful to remember approx. 3300 for hydroxyl and approx. 1700 for carbonyl (C=O).
The Medical College Admissions Test (MCAT) is a test administered by the Association of American Medical Colleges (AAMC). The test is designed to test your knowledge in three specific sections; physical sciences such as physics and general chemistry, biological sciences and organic chemistry, and verbal reasoning.
How Should I Study?
The MCAT is a rigorous exam that requires months of planning in order to achieve a great score. It is recommended that you begin your study schedule 3 months prior to your exam date. In addition to answering our practice MCAT questions each day, read this article regarding studying for the MCAT from home.
Register for the MCAT.
The first question many people ask is, “when should I take the MCAT?” The general guideline is to take the MCAT the year before you plan to enter medical school. For example, the class of 2018 should take the MCAT sometime before or during the spring/summer of 2013. Your basic science coursework should be complete by this point.
