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. Rotations cancel each other out therefore no optical activity






2. One s and three p orbitals






3. Most favorable of staggared conformations






4. Diols with hydroxyl group on adjacent carbon






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






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






7. Refers to the =CH2 group






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






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






10. Name for propanal






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






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






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






15. A = observed rotation / concentration * length






16. Not solvated






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






18. Iso - neo - cyclo






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






20. Charged - need electrons






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






22. Monosubstituted ethylene






23. Di - tri - t - sec - n -






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






25. What is produced when o3 with lialh4 or nabh4






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






27. What are the best leaving groups?






28. Zn/h or CH3/s with ozonolysis






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






30. Diol with hydroxyl group on same carbon






31. Hydrocarbon with one or more carbon carbon triple bond






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






33. 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.






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






35. Formed by mixing different types of orbitals






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






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






38. 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






39. 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






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






41. Alphabetical order of alkane rxn






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






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






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






45. Compounds with halogen






46. Lowest priority group projects into the page






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






48. Carbon carbon triple bonds. Suffix-yne.






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






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