Help ASAP Illustrate the resonance effect of the methoxy group -OCH3, on the structure of the benzene ring. Do this by writing all the possible resonance forms for methoxybenzene, including the hybrid. Based on your structures, explain how the presence of the -OCH3 group affects: (i) the reactivity of the benzene ring towards electrophilic attack; (ii) the orientation or point of attack of an incoming electrophilic reagent on the benzene ring.

Draw the product of nucleophile substitution , and determine the likely mechanism ( SN1 or SN2

Draw the most stable resonance form for the intermediate in the following electrophilic substitution reaction. CH3 CH3 H3PO4 HO, + H3C CH3 HO HO First stage in synthesis of the epoxy and polycarbonate ingredient bisphenol-A You do not have to consider stereochemistry. Include all valence lone pairs in your answer. In cases where there is more than one answer, just draw one.

Propose a mechanism for the conversion of E to F. The reagent used in this synthesis is ethyl chloroformate. The other product of this conversion is chloromethane, CH3Cl. Your mechanism should show how the CH3Cl is formed.

In EAS bromination reactions, a -CON(CH3)2 substituent on the aromatic ring is: an activator and an o,p-director. a deactivator and a m-director. an activator and a m-director. the substituent catalyzes the 1,2 addition of bromine across the double bond. a deactivator and an o,p-director. G

(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

Predict the product and draw the mechanism of its formation. Include lone pairs and charges in your answer. Using wedges and dashes to indicate the stereochemistry as necessary. Do not use abbreviations such as Me or Ph in your drawings. Do not explicitly draw any hydrogen atoms in any of your products. & Me 13.16d1 1) LIAIH. 2) H₂O Draw the first step of the mechanism (Use H as the nucleophile). CH, +H Edit Drawing

The synthesis above used bromoethane, but acetylene is the only allowed source of carbon atoms. Using the reagents given, identify a synthetic route for the production of bromoethane from acetylene. The transformation above can be performed with some reagent or combination of the reagents listed below. Give the necessary reagent(s) in the correct order, as a string of letters (without spaces or punctuation, such as "EBF"). If there is more than one correct solution, provide just one answer.

An organic chemistry experiment involves a nucleophilic substitution (SN2) reaction using 1-iodobutane and 2-naphthoxide ion. The 2-naphthoxide ion is generated from 2-naphthol and sodium hydroxide in an ethanol solvent. The experiment includes steps like generating the nucleophile, conducting the SN2 reaction, and analyzing the product using 1H NMR spectroscopy. Question: Write the structure of the undesired side product if CH3CH2O‾ (ethoxide) reacts with 1-iodobutane.
