Deduce the identity of the following compound from the spectral data given. C8H10: 1H NMR, 6 1.20 (3H, triplet), 2.60 (2H, quartet), 7.12 (5H, singlet) (ppm); IR, 3050, 2970, 1600 cm-1; MS, m/z 91
Compound I (C11H14O2) is insoluble in water, aqueous acid, and aqueous NaHCO3, but dissolves readily in 10% Na2CO3 and 10% NaOH. When these alkaline solutions are acidified with 10% HCl, compound I is recovered unchanged. Given this information and its 1H-NMR spectrum, deduce the structure of compound I.

Conjugate base acid Cyclopentadiene pKa 1) Consider the reaction AH(+) + H₂O →> A:+H3O+. For the following named acids: 1) draw the structure of the acid, 2) give the approximate pKa of the conjugate acid (±1 pKa unit), 3) give the name of the conjugate base, and 4) draw the structure of the conjugate base. For the purposes of answering this question you may use pKa values evenly divisible by 5. p-Methoxyanilinium cation pKa Benzenesulfonic acid Butanal pKa pKa
Many biochemical reactions utilize cationic imines (a Schiff base) as electron sinks. Illustrate your understanding of this concept by drawing the mechanism of basic imine formation between an aldehyde (RCHO) and an amine (RNH2). For full credit, you must show all electron flow (using the arrow convention).
Compound A (C10H14) shows prominent peaks in its mass spectrum at m/z 134 and 91. Compound B (also C10H14) shows prominent peaks at m/z 134 and 119. On vigorous oxidation with chromic acid, compound A gave benzoic acid, but compound B was nonreactive. From this information, deduce the structures of both compounds, and then draw the structure of A. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. Do not include lone pairs in your answer. They will not be considered in the grading.
Aniline (conjugate acid pKa 4.63) is a considerably stronger base than diphenylamine (pKa 0.79). Account for these marked differences.

1,3,5,7-Cyclooctatetraene, C8H8, is an unusual hydrocarbon in that it reacts with exactly 2 equivalents of potassium to give A, C8H8K2, which can be isolated as a white solid. A exhibits a single proton NMR signal. Draw the structure of A.
(a) Tsomane and Nyiko were given a task of synthesising methylenecyclohexane 2. After a brief discussion with each other, Tsomane proposed Method A to synthesise 2 from cyclohexanone 1 while Nyiko proposed Method B that started from hydroxymethylcyclohexane 3. Each student believed that their proposed method is better than the other. (Scheme below) Ph THF A Ph Ph B H₂SO4 100 °C 3 OH (iii) In analysing both these methods, are there other possible alkene products other than methylenecyclohexane 2?
