3. Please provide a reasonable mechanism for the following transformation. Include all intermediates, formal charges, and arrows depicting electron flow. You do not need to include all resonance forms in your answer. Me Me ہی ملی .Me NaOH H₂O, heat

The nitro groups on the benzene ring in the reactant serve two purposes.One is to let you know what atoms in the reactant correspond to what atomsin the product. But what role do the nitro groups play electronically – whywould the reaction be much slower if these nitro groups weren’t attached tothose benzene carbons? Draw any relevant structures to support youranswer.

When ethoxybenzene is treated with a mixture of nitric acid and sulfuric acid, two products are obtained, each of which has the molecular formula C8H9NO3.For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer.  Do not draw out any hydrogen explicitly in your products. Do not use abbreviations such as Me or Ph.

Draw a structural formula of an alkene or alkenes (if more than one) that undergo acid-catalyzed hydration and without rearrangement give 1-methylcyclohexanol as the major product. • You do not have to consider stereochemistry. • You do not have to explicitly draw Hatoms. • If more than one structure fits the description, draw them all. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu. ● 8) *9.8 MUIT / ? ChemDoodle [ ] remove

11) Show the complete reaction mechanism for the following. Show any resonance stabilization of charges if applicable. Do not draw anything directly on the reaction scheme below.... redraw all structures from scratch. & -OH NaOH Ethanol + H₂O

Help me please

(a) In an acid-catalyzed hydration, one of the following 10 carbon alkynes is expected to produce a single hydration product? Select the correct alkyne and draw the structure of the hydration product that is formed from this alkyne. (I) 2-decyne; (II) 3-decyne; (III) 4-decyne; (IV) 5-decyne; (V) none of these will give a single hydration product. (b) The reaction shown below gives Compound X as the major product. The mass spectrum of X is shown. Br2, H20 Compound X 100 - MS-IW-5644 80 60 40 - 20 - 20 40 60 80 100 120 140 160 180 200 220 m/z Considering the reactions of alkynes and the MS data, de duce which of following structures corresponds to X: Br Br HO, IV V I II II Support your answer with a reaction mechanism for fomation of X and identification of relevant peaks in the mass spectrum. 12 Relative Intensity
