25 Questions

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

2. Two hydroxyl groups

3. Diol with hydroxyl group on same carbon

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

5. Name for propanal

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

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

8. Iso - neo - cyclo

9. Charged - need electrons

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

11. Lowest priority group projects into the page

12. Name for ethanal

13. 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

14. Diols with hydroxyl group on adjacent carbon

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

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

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

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

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

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

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

22. Most favorable of staggared conformations

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

24. What are the best leaving groups?

25. 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.
