- An important step in one synthesis of carboxylic acids is the deprotonation of diethyl malonate and its alkyl-substituted derivative: Base CH;CH2O OCH,CH3 CH;CH,0 OCH2CH3 H2 Diethyl malonate Base CH;CH,0 °C `OCH,CH3 CH;CH,O OCH,CH3 R Alkyl substituted diethyl malonate NaOH can deprotonate diethyl malonate effectively, but NaOC(CH3)3 is typically used to deprotonate the alkyl-substituted derivative. Explain why.Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonation of the alcohol oxygen to form an oxonium ion. Dehydration of 3-methyl-2-butanol forms one major and two minor organic products. Draw the structures, including hydrogen atoms, of the three organic products of this reaction. н н :бн н Нас. Нас.

Make sure to use the same skeletal ("line") style for the structure as the rest of the equation.Phenol and other derivatives with a single hydroxyl group on the aromatic ring are not easily oxidized to form a ketone. Why is this? Select all that apply: O Phenol is a secondary alcohol; secondary alcohols do not oxidize. O The carbon that the hydroxyl group is attached to in phenol does not have a hydrogen attached. Forming a double bond between the oxygen and the carbon would require breaking up the stable aromatic ring. Phenol is a tertiary alcohol, which does not oxidize.
- What is the slow, rate-determining step, in the acid-catalyzed dehydration of 2- butanol? Loss of a b-hydrogen from the carbocation to form an alkene. Protonation of the alcohol to form an oxonium ion. Loss of water from the oxonium ion to form a carbocation. The simultaneous loss of a B-hydrogen and water from the oxonium ion.From the table of available reagents select the one(s) you would use to convert: 3-pentanol to 3-bromopentane. 3-pentanol to 3-methylpentane.
