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






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






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






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






5. Name for propanal






6. Lowest priority group projects into the page






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. Methyl are 60 degrees apart. kinda stable






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






10. Goal is to produce most stable carbocation

11. N - l - ml - ms






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






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






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






15. Carbon double bonded to an oxygen






16. Rotations cancel each other out therefore no optical activity






17. Object that is not superimposable upon mirror image






18. Compounds with halogen






19. Contain carbon carbon double bonds. Use same root of alkane but end with 'ene'






20. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






21. When boat flips






22. Zn/h or CH3/s with ozonolysis






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






24. Sharing of electron between atoms






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






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






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






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






29. 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.






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






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

32. 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






33. Formed by mixing different types of orbitals






34. Highest energy no separation. or 120 separation.






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






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






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






38. Name for ethanal






39. Diols with hydroxyl group on adjacent carbon






40. 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-






41. Most favorable of staggared conformations






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






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






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






45. Hydrocarbon with one or more carbon carbon triple bond






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






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






48. Alphabetical order of alkane rxn






49. Carbon carbon triple bonds. Suffix-yne.






50. A = observed rotation / concentration * length
