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. Two hydroxyl groups






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






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






4. Refers to the =CH2 group






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






6. Highest energy no separation. or 120 separation.






7. Hydrocarbon with one or more carbon carbon triple bond






8. Diols with hydroxyl group on adjacent carbon






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






10. Transfer of electrions from one atome to another






11. Lowest priority group projects into the page






12. Compounds with halogen






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






14. Not solvated






15. Formed by mixing different types of orbitals






16. Combustion reaction occurs through a radical process






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






18. Methyl are 60 degrees apart. kinda stable






19. Iso - neo - cyclo






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






21. Goal is to produce most stable carbocation

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






23. What is produced when o3 with lialh4 or nabh4






24. 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.






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






26. 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






27. Charged - need electrons






28. 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






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






30. When bond angles deviate from ideal values






31. F - CL - Br - I






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. Same molecular formula but different structure






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






35. Rotations cancel each other out therefore no optical activity






36. A molecule with an internal plane of symmetry






37. Name for propanal






38. Di - tri - t - sec - n -






39. N - l - ml - ms






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






41. Zn/h or CH3/s with ozonolysis






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






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






44. Steps of free radical substitution






45. Functionality is specified by alkoxy- prefix. ROR






46. One s and three p orbitals






47. Name for mathanal






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






49. O3






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