Look up the structures of uracil and thymine in the McMurry book. Draw them, and describe how they are different Look up the structures of homocysteine and methionine in the McMurry book. Draw them, and describe how they are different. Tetrahydrofolic acid is used to transfer methyl groups. Look up the structure of tetrahydrofolic acid and draw it. (A good source is PubMed] Look up the structure of folic acid [in PubMed] and describe how...
c. Mg ules for drawing Lewis Structures: Count up all the valence electrons and add them up. Arrange atoms in a bonding conf round the outside. guration. Least electronegative atom typically goes in the midle. H gets arra g . Put the electron in- 2 electrons for each single bond between atoms. Put extra electrons ut any extra there. on outer atoms that can accept them as lone pairs. Hydrogen can only have two electrons so . Check that each...
(4 pts) Hydroboration of 1-methylcyclopentene (1) is regioselective; trans-2-methylcyclopentyl borane (2) is the major product. Draw two transition state structures for the hydroboration of 1 in the boxes provided that account for each alkyl borane 2 & 3. Use dotted lines (-----) to indicate partial bond formation and partial bond cleavage. Indicate partially positive and partially negative atoms with delta signs (8+ & d).
