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. One s and two p 120 degree apart






2. Methyl are 60 degrees apart. kinda stable






3. Functionality is specified by alkoxy- prefix. ROR






4. Zn/h or CH3/s with ozonolysis






5. Kmno4






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






7. Carbon double bonded to an oxygen






8. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes






9. Name for propanal






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






11. 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.






12. Highest energy no separation. or 120 separation.






13. O3






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. A = observed rotation / concentration * length






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






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






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






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






20. Object that is not superimposable upon mirror image






21. Hydrocarbon with one or more carbon carbon triple bond






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






23. A radical transfers a hydrogen atom to another radical and makes an alkane and alkene






24. Is bonded to only one other carbon atom






25. F - CL - Br - I






26. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






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






28. 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






29. 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-






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






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






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






33. Formed by mixing different types of orbitals






34. Refers to the =CH2 group






35. Transfer of electrions from one atome to another






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






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






38. When boat flips






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






40. Diol with hydroxyl group on same carbon






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






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






43. 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.






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






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






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






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






48. If reagent has a bunch of oxygen






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






50. Steps of free radical substitution
