What type of reaction requires the addition of energy to go to completion?
Endothermic reactions require the addition of energy to go to completion. This means that for the reactants to form products, energy must be absorbed from the surroundings.
What reaction does aconitase catalyse?
The isomerisation of citrate to isocitrate in the TCA cycles
Why is there an incubation step after the addition of the substrate in ELISA reactions?
There needs to be a conversion of the substrate for the chemical reaction to provide an H+ ion for the color change needed for ELISA. The temperature essentially lowers the activation energy to allow for this reaction to proceed.
Does A dehydration reaction that builds larger molecules from smaller units requires the addition of a water molecule?
Yes, a dehydration reaction joins smaller molecules by removing a water molecule. This process results in the formation of larger molecules and the release of a molecule of water as a byproduct.
What is one product of the light-dependent reaction?
The light dependent reaction produces two useful substances for the plant: ATP and NADPH. In addition it produces a waste product, oxygen gas. The ATP and the NADPH are then used in the light independent reaction. The oxygen is released into the atmosphere.
What kind of reaction occurs when Br and cyclohexene are mixed?
It's called an addition reaction. Specifically, it's an electrophilic addition reaction.
Cyclopentene with bromine?
Cyclopentene + bromine => 1,2-dibromocyclopentane
Why is the reaction of ethene and chlorine not a free-radical addition reaction?
The reaction of ethene and chlorine is not a free-radical addition reaction because it proceeds via an electrophilic addition mechanism. The π electrons of ethene attack the electrophilic chlorine molecule, leading to the formation of a cyclic intermediate called a chloronium ion. This is followed by the attack of a chloride ion to give the final product.
The reaction in which propene is converted to 2-chloropropane is?
The reaction in which propene is converted to 2-chloropropane is an electrophilic addition reaction with hydrogen chloride (HCl) in the presence of a catalyst like a peroxide. The double bond in propene acts as a nucleophile, attacking the electrophilic hydrogen of HCl to form 2-chloropropane.
What type of reaction is Cyclohexene and Bromine?
Electrophilic addition. Forms 1,2,-dibromocyclohexane
Why carbonyl compounds undergo nucleophilic addition reactions?
Carbonyl compounds are electrophilic due to the partially positive carbon atom. Nucleophiles are attracted to this electrophilic carbon atom, leading to a nucleophilic addition reaction. The nucleophile attacks the carbonyl carbon, forming a tetrahedral intermediate, which then collapses to form the final product.
What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
What is the mechanism of electrophilic addition of HBr to an alkene?
The mechanism of electrophilic addition of HBr to an alkene involves the alkene acting as a nucleophile attacking the electrophilic hydrogen of HBr, forming a carbocation intermediate. The bromide ion then attacks the carbocation, resulting in the addition of H and Br across the double bond.
Why alkanes do not react with bromine water?
Alkanes do not react with bromine water because alkanes are saturated hydrocarbons, meaning they have only single bonds between carbon atoms. This makes them relatively unreactive towards electrophilic addition reactions, such as the reaction with bromine water. bromine water reacts with alkenes, which have carbon-carbon double bonds, through an electrophilic addition reaction.
What is produce when 1-butene reacts with hcl?
When 1-butene reacts with HCl, the product formed is 2-chlorobutane. This reaction proceeds through an electrophilic addition mechanism.
What is Reaction of triethyl phosphite with aidehyde?
Triethyl phosphite reacts with aldehydes to form β-hydroxy phosphonates via a Pudovik reaction. This reaction involves the addition of the phosphite to the carbonyl group of the aldehyde, followed by a dehydration step to yield the β-hydroxy phosphonate product.
Do ester react with bromine?
Yes, esters can react with bromine in the presence of a Lewis acid catalyst to undergo electrophilic aromatic substitution, resulting in the addition of bromine atoms to the ester molecule. This reaction is known as the Hunsdiecker reaction.
