- which statement is true in the e2 reaction of the given compounds with NaOCH2CH3?arrow_forwardin a reaction where trans-stilbene reacts with a molecule of bromine while using ethanol as a solvent, what would happen if the ethanol was a more reactive nucleophile than the bromide ion(s)? would the product be affected?arrow_forwardexplain some of the hazards (name at least three) involved in the Friedel-Crafts Acylation: Synthesis of 4-methoxyacetophenone from anisole experiment. What are some necessary safety precautions when working with aluminum chloride? List compounds that react in a hazardous manner with aluminum chloride and are therefore incompatible. What hazardous by-products are formed in this experiment? Why is it necessary to perform this experiment in the fume hood?arrow_forward
- What would be the product of a reaction involving 2-methyl-2-pentene and HBr both with and without the presence of peroxides?arrow_forwardWhat product would you obtain if you evaporated the water from the NaOH layer prior to acidifying the layer? (we are trying to extract p-tert-butylphenol; it is in aqueous solution with NaOH, which we used to extract it from a mixture dissolved in ether). Prior to acidifying with HCl, it is ionic (phenoxide).arrow_forwardIf a large excess of the nitrating reagent is added, does the product produced contain one nitro group or more than one?arrow_forward
- in a reaction where trans-stilbene reacts with a molecule of bromine while using ethanol as a solvent, what would happen if the ethanol was a more reactive nucleophile than the bromide ion(s)? what would the product look like?arrow_forwardWhich experimental method would you recommend for the preparation of 1-bromooctane and of t-butyl bromide?arrow_forwardWhy is diethyl ether used as a solvent for the reduction reaction of the keystone (3,3-dimethyl-2-butanone) utilizing the reducing agent sodium borohydride (NaBH4). what is the purpose of was repeated washes with water? What is the purpose of repeated washes with brine?arrow_forward
- Which of the following choices represents the correct mechanistic steps when butyraldehyde (butanal) is added to acidic water (i.e., water that has a strong acid such as H2SO4 added to it), and, to some extent, a hydrate is formed? Use the following numbering scheme: 1 = p.t., 2 = Nu attack, 3 = Loss of LG, 4 = no reaction. O 1, 2, 1 О 1,2, 3, 1 О 2, 1, 3, 1 О 2, 1, 2 O 2,1 O 1, 2arrow_forwardIn which case will you be running into a risk forming a cross-linked polyester, and why?arrow_forwardWrite the formula for a reagent that will form PbCrO4 with Pb(NO3)i.arrow_forward
