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






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






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






4. One s and three p orbitals






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






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






7. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






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






9. Name for ethanal






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






11. Diol with hydroxyl group on same carbon






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






13. Transfer of electrions from one atome to another






14. Two hydroxyl groups






15. Hydrocarbon with one or more carbon carbon triple bond






16. M - chloroperoxybenzoic acid






17. Formed by mixing different types of orbitals






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






19. When two atomic orbitals combine. obtained mathematically by adding or subtracting wave functions. if sings are the same - make bonding - if different - less stable antibonding.






20. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






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






22. Di - tri - t - sec - n -






23. Kmno4






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






25. Name for mathanal






26. 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






27. 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






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






29. Steps of free radical substitution






30. A sigma bond and two pi bonds






31. Same molecular formula but different structure






32. A molecule with an internal plane of symmetry






33. F - CL - Br - I






34. 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.






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






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






37. Combustion reaction occurs through a radical process






38. Common name for ethyne






39. Sharing of electron between atoms






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






41. Functionality is specified by alkoxy- prefix. ROR






42. Object that is not superimposable upon mirror image






43. When boat flips






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






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






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






47. 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-






48. Zn/h or CH3/s with ozonolysis






49. Not solvated






50. N - l - ml - ms
