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. 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






2. Combustion reaction occurs through a radical process






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






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






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






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






7. If reagent has a bunch of oxygen






8. N - l - ml - ms






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






10. A sigma bond and two pi bonds






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






12. Zn/h or CH3/s with ozonolysis






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






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






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






16. Object that is not superimposable upon mirror image






17. O3






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






19. Hydrocarbon with one or more carbon carbon triple bond






20. Compounds with halogen






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






22. Sharing of electron between atoms






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






24. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

25. Kmno4






26. 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






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






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






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






30. Iso - neo - cyclo






31. Most favorable of staggared conformations






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






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






34. Rotations cancel each other out therefore no optical activity






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






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






37. Charged - need electrons






38. Steps of free radical substitution






39. 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-






40. One s and three p orbitals






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






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






43. Name for ethanal






44. When bond angles deviate from ideal values






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






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






47. Highest energy no separation. or 120 separation.






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






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






50. Is bonded to only one other carbon atom
