MCAT Organic Chemistry

Subjects : mcat, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






2. Nonsuperimposable mirror image of chiral objects - a specific steroisomer.






3. Results when cyclic molecules must assume conformations that have eclipsed interactions






4. If a compound is able to rotate plane polarized light.






5. Name for propanal






6. Cleaves double bond in half - it only oxidizes the carbon to an aldehyde under reducing conditions. if ozidizing make same product as KMNO4






7. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






8. Y = position of double bond - x is position of triple bond - root is the prefix representing the length of the principal carbon chain






9. Use the Greek root for the number of carbons followed by the ending - - ane






10. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






11. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






12. Non mirror image of configurational isomers. cis and trans alkenes are them. possible when a molecule has two or more stereogenic centers that differ at some but not alll of the centers. they require multiple chiral centers.






13. Spatial arrangement of the atoms or groups of a sterioisomer






14. Common name for ethyne






15. Goal is to produce most stable carbocation

16. When boat flips






17. Alkenes oxidzed with kmno4 - if made with cold - dilue - make OH on each side of double bond - diols or glycol in syn orientation






18. Charged - need electrons






19. Creation of long - high molecular weight polymer composed of repeating subunit called monomers. occur through a radical mechanism.






20. When bond angles deviate from ideal values






21. What is produced when o3 with lialh4 or nabh4






22. Carbonyl located at the end of the chain named by replacing al with e. e.g. butanal






23. Contain carbon carbon double bonds. Use same root of alkane but end with 'ene'






24. Reaction of alkane with oxygen to form carbon dioxide - water and heat.






25. Carbon carbon triple bonds. Suffix-yne.






26. Functionality is specified by alkoxy- prefix. ROR






27. Ozonolysis under hot acidic kmO4 - e.g. H2O2 condition






28. Share molecular formula but have different chemical and physical properties






29. Kmno4






30. Lowest priority group projects into the page






31. Diborane add to double bond. boron acts as lewis acid and attaches to less hindered carbon. hydride transferred to adjacent carbon. antimarkonikov - alcohol produced






32. N - l - ml - ms






33. A = observed rotation / concentration * length






34. Always receive number one. contain carbonyl and OH group - very oxidized. highest priority functional group.






35. No double bonds. it has the maximum number of hydrogens.






36. Arise from angle strain - torsional strian and nonbonded strain






37. When two atomic orbitals combine. obtained mathematically by adding or subtracting wave functions. if sings are the same - make bonding - if different - less stable antibonding.






38. One s and two p 120 degree apart






39. Nucleus lover. electron rich species that are attracked to charged atoms






40. Sharing of electron between atoms






41. Zn/h or CH3/s with ozonolysis






42. Methyl are 60 degrees apart. kinda stable






43. Propylenes attached to a backbone at the C-3 position. Meaning the double bond at end of the chain and single bonded carbon at rest






44. Most similar. same molecule only at different points in their rotation. show them with newmans projections






45. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






46. Object that is not superimposable upon mirror image






47. If reagent has a bunch of oxygen






48. Hydrocarbon with one or more carbon carbon triple bond






49. Is bonded to only one other carbon atom






50. Carbon with four different substituents and lack a plane of symmetry
