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






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






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






4. Diol with hydroxyl group on same carbon






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






6. Name for mathanal






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. Functionality is specified by alkoxy- prefix. ROR






9. Most favorable of staggared conformations






10. Carbon carbon triple bonds. Suffix-yne.






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






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






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






14. Sharing of electron between atoms






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






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






17. Object that is not superimposable upon mirror image






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






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






20. Is bonded to only one other carbon atom






21. Not solvated






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






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






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






25. Iso - neo - cyclo






26. Charged - need electrons






27. Carbon double bonded to an oxygen






28. Formed by mixing different types of orbitals






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






30. 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.






31. What is produced when o3 with lialh4 or nabh4






32. When boat flips






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






34. Diols with hydroxyl group on adjacent carbon






35. Di - tri - t - sec - n -






36. Refers to the =CH2 group






37. Common name for ethyne






38. N - l - ml - ms






39. Transfer of electrions from one atome to another






40. Lowest priority group projects into the page






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






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






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






44. Same molecular formula but different structure






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






46. Steps of free radical substitution






47. What are the best leaving groups?






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






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






50. When bond angles deviate from ideal values
