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. Alphabetical order of alkane rxn






2. One s and three p orbitals






3. Carbon carbon triple bonds. Suffix-yne.






4. Kmno4






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






6. Steps of free radical substitution






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






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






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






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






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






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






13. Rotations cancel each other out therefore no optical activity






14. Highest energy no separation. or 120 separation.






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






16. Name for propanal






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






18. 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.






19. When bond angles deviate from ideal values






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






21. Carbon double bonded to an oxygen






22. 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






23. Functionality is specified by alkoxy- prefix. ROR






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






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






26. A molecule with an internal plane of symmetry






27. Common name for ethyne






28. Formed by mixing different types of orbitals






29. Sharing of electron between atoms






30. Monosubstituted ethylene






31. Two hydroxyl groups






32. One s and two p 120 degree apart






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






34. Methyl are 60 degrees apart. kinda stable






35. What is produced when o3 with lialh4 or nabh4






36. Diol with hydroxyl group on same carbon






37. N - l - ml - ms






38. Not solvated






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






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






41. If reagent has a bunch of oxygen






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






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






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






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






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






47. Diols with hydroxyl group on adjacent carbon






48. Object that is not superimposable upon mirror image






49. Name for mathanal






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