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






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






3. Iso - neo - cyclo






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






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






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






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






8. Carbon double bonded to an oxygen






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






10. O3






11. Steps of free radical substitution






12. One s and two p 120 degree apart






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






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






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






16. A molecule with an internal plane of symmetry






17. M - chloroperoxybenzoic acid






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






19. A sigma bond and two pi bonds






20. Two hydroxyl groups






21. Zn/h or CH3/s with ozonolysis






22. Diols with hydroxyl group on adjacent carbon






23. Common name for ethyne






24. 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






25. Rotations cancel each other out therefore no optical activity






26. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






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






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






29. Carbon carbon triple bonds. Suffix-yne.






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






31. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






32. Not solvated






33. When two p orbitals line up in parallel and electron clouds overlap. it exsits over a single bond.






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






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






36. Is bonded to only one other carbon atom






37. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






38. What is produced when o3 with lialh4 or nabh4






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






40. 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






41. Differ in position of substitutents attached to a double bond or cycloalkane. Cis or trans or e or z






42. Monosubstituted ethylene






43. Moleculse that have the opposite configuration at their one chiral center. or if multiple chiral centers - must have the opposite configuration at every one of their chiral centers to be enantiomers. identical physical properties and much of the same






44. One s and three p orbitals






45. 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-






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






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






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






49. 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.






50. Methyl are 60 degrees apart. kinda stable
