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. Carbonyl located in middle or somewhere in chane. Named with One






2. Steps of free radical substitution






3. How many stereoisomers can a molecule have with n chiral centers






4. 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.






5. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






6. Monosubstituted ethylene






7. Combustion reaction occurs through a radical process






8. Alphabetical order of alkane rxn






9. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






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






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






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






13. 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.






14. E of double bond act as lewis base and react with hydrogen of hx. make carbocation intermediate. use markonikovs rule






15. When bond angles deviate from ideal values






16. F - CL - Br - I






17. Is bonded to only one other carbon atom






18. Not solvated






19. A = observed rotation / concentration * length






20. Nitrogen containing compound - longest chain attached to nitrogen used in backbone. use e and replace with AMINE. if more complex molecule present - use prefix amino. IF additional group added - use N-






21. Two hydroxyl groups






22. Same chemical formula. same atomic connectivity . different in how atoms are arranged in space






23. Iso - neo - cyclo






24. One s and two p 120 degree apart






25. Formed by mixing different types of orbitals






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






27. A sigma bond and two pi bonds






28. Carbon carbon triple bonds. Suffix-yne.






29. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






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






31. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






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






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






34. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






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






36. Chain of carbons connected by single bonds with hydrogen atoms attached.






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






38. When boat flips






39. Methyl are 60 degrees apart. kinda stable






40. Name for ethanal






41. One s and three p orbitals






42. M - chloroperoxybenzoic acid






43. Name for propanal






44. Diols with hydroxyl group on adjacent carbon






45. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






46. If reagent has a bunch of oxygen






47. Name for mathanal






48. Di - tri - t - sec - n -






49. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






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