6. Which homologous series has the functional group -COC-?
- ketones
- aldehydes
- esters
- alcohols
7. How many carbon atoms in 3-ethyl-2,3-dimethylpentane
8. What are isomers?
- Two molecules that has the same molecular formula and their atoms are arrange the same
- Two molecules that are totally different
- Two molecules that have the same molecular formula but their atoms are arranged differently
- Two molecules that have the same functional group but a different molecular formula
9. What are stereoisomers?
- Same structural formula but different arrangement in space
- Same arrangement but with different number of bonds
10. Which homologous series has the functional group CHO?
- esters
- ketones
- aldehydes
- acyl chlorides
11. If 2 atoms are the same, when working out priorities of groups attached to a C=C bond, what do you do?
- They cannot be the same, check your working
- Look at the next atom along that they are attached to and whichever has largest molecular formula has highest prioty
- Find an average, eg if determining priorities 2 and 3, they both has priority 2.5
12. Which homologous series has the functional group -COCl?
- acyl chlorides
- arenes
- halogenoalkanes
- halogens
13. What are chain isomers?
- They have a different arrangement of the carbon skeleton
- Same skeleton and same atoms/groups attached but that the atom or groups of atoms is attached to different carbon atom
- Same atoms arranged into different functional groups
14. Cycloalkanes have the same general formula as....?
- arenes
- alkenes
- ketones
- branched alkanes
15. What is the definition of empirical formula?
- An algebraic formula that can describe any member of a family of compounds
- The simplest ratio of atoms in a compound
- The actual number of atoms of each element in a molecule
- Shows the atoms carbon by carbon, with the attached hydrogens and functional group
16. What system is used for naming organic compounds?
17. Which homologous series is named with the suffix '-al'?
- alcohols
- aldehydes
- alkenes
- ketones
18. A molecule has the stem 'but-' if its carbon chain is.... carbons long
19. What does a E-isomer have?
- The two highest priority groups on opposite sides of the C=C bond
- The two highest priority groups on the same side of the C=C bond
20. What is the functional group for carboxylic acids?
