Answer #1

Mechanism shows hydroxyl at C1 gets protonated first and then after removal of H2O, carbocation gets stabilized by oxygen. nitrogen from purinebor pyrimidine attack on C1.

    Which of the following statements is NOT true about phenol? Select the correct answer below: The aromatic ring delocalizes and stabilizes the negative charge on the oxygen in the phenoxide ion. Therefore, phenols completely dissociate in water. A phenol will generally form stronger hydrogen bonds than nonaromatic alcohols because the oxygen-hydrogen dipole in the hydroxyl group is stabilized by resonance from the aromatic ring. The phenol functional group is a weak acid in water because the hydroxyl group dissociates slightly....

    8) Draw a mechanism with all the proper arrows for the reaction from this experiment. Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both...
