The oxygen atom between the C and H atoms should be circled, and is sp3 hybridized. There is an extra hydrogen atom on the middle carbon of the structure on the left. 14, 1.16 Is misnumbered as 1.15 Pg. 34, Problems 1.60, 1.61 and 1.62 should be renumbered as 1.62, 1.60 and 1.61, respectively. 79, 3.12d Should be boric acid, not acetic acid.
Boric acid is stronger.
155, 6.31 Mechanism should involve an iodonium ion, not free carbocation. 204, 8.8a Should be E2 not SN2, leading to an alkene, not the ether shown. The pKa of ammonia is 38, not 33. The pKa of ammonia should be 38, not 33. 651, 20.38 Synthesis should start with phenol via Kolbe reaction.
