- 2-bromo-2-methylbutane undergoes hydrolysis reaction with water, H2O toform compound W. Compound X and compound Y are produced when 2-bromo-2-methylbutane undergoes elimination reaction with alcoholic ofsodium hydroxide, NaOH. (i) Draw the structural formula of compounds W, X and YMention and Write the following reaction mechanisms: a) thermal dehydration of 4-t-butylcyclohexanol with phosphoric acid as catalyst; b) addition of molecular bromine to the C= C double bond of 4-t- butylcyclohexene;Show how you would synthesize the following compounds, starting with benzene or toluene and any necessary reagents. Assume para is the major product (and separable from ortho) in ortho, para mixtures. a) 1-phenypentane b) p- bromobenzene sulfonic acid c) o- chlorobenzonic acid d) m- chloronitrobenzene
- Amines are converted into alkenes by a two-step process called Hofmann elimination. SN2 reaction of the amine with an excess of CH3I in the first step yields an intermediate that undergoes E2 reaction when treated with silver oxide as base. Pentylamine, for example, yields 1-pentene. Propose a structure for the intermediate, and explain why it readily undergoes elimination.The base-promoted rearrangement of an -haloketone to a carboxylic acid, known as the Favorskii rearrangement, is illustrated by the conversion of 2-chlorocyclohexanone to cyclopentanecarboxylic acid. It is proposed that NaOH first converts the a-haloketone to the substituted cyclopropanone shown in brackets and then to the sodium salt of cyclopentanecarboxylic acid. (a) Propose a mechanism for base-promoted conversion of 2-chlorocyclohexanone to the proposed intermediate. (b) Propose a mechanism for base-promoted conversion of the proposed intermediate to sodium cyclopentanecarboxylate.A. In the synthesis of 1-bromobutane, what is the inorganic by-product left in the reaction flask following the distillation? Why was the bromoalkane the bottom layer in the separatory funnel? B.

- Compound A (C7H11Br) is treated with magnesium in ether to give B (C7H11MgBr), which reacts violently with D2O togive 1-methylcyclohexene with a deuterium atom on the methyl group (C). Reaction of B with acetone (CH3COCH3)followed by hydrolysis gives D (C10H18O). Heating D with concentrated H2SO4 gives E (C10H16), which decolorizestwo equivalents of Br2 to give F (C10H16Br4). E undergoes hydrogenation with excess H2 and a Pt catalyst to giveisobutylcyclohexane. Determine the structures of compounds A through F, and show your reasoning throughoutCompound A (C7H11Br) is treated with magnesium in ether to give B (C7H11MgBr), which reacts violently with D2O to give 1-methylcyclohexene with a deuterium atom on the methyl group (C). Reaction of B with acetone (CH3COCH3) followed by hydrolysis gives D (C10H18O). Heating D with concentrated H2 SO4 gives E (C10 H16), which decolorizes two equivalents of Br2 to give F (C10H16 Br4). E undergoes hydrogenation with excess H2 and a Pt catalyst to give isobutylcyclohexane. Determine the structures of compounds A through F, and show your reasoning throughout.Treatment of cis-4-bromocyclohexanol with HO− affords compound Aand cyclohex-3-en-1-ol.
