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






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






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






4. Iso - neo - cyclo






5. Name for propanal






6. Compounds with halogen






7. Carbon double bonded to an oxygen






8. Sharing of electron between atoms






9. Name for mathanal






10. Diol with hydroxyl group on same carbon






11. Steps of free radical substitution






12. 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






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






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






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






16. Methyl are 60 degrees apart. kinda stable






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






18. 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






19. Monosubstituted ethylene






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






21. Carbon carbon triple bonds. Suffix-yne.






22. One s and two p 120 degree apart






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






24. Refers to the =CH2 group






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






26. 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.






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






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






29. When bond angles deviate from ideal values






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






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






32. When a molecular orbital is formed head to head or tail to tail. all single bonds are tehese.






33. M - chloroperoxybenzoic acid






34. Object that is not superimposable upon mirror image






35. 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-






36. Formed by mixing different types of orbitals






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






38. Most favorable of staggared conformations






39. Common name for ethyne






40. Not solvated






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






42. A sigma bond and two pi bonds






43. Alphabetical order of alkane rxn






44. One s and three p orbitals






45. Same molecular formula but different structure






46. Charged - need electrons






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






48. Transfer of electrions from one atome to another






49. Di - tri - t - sec - n -






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