3. Give the order of reactivity of the alkyl halides you reacted with aqueous silver nitrate. Does this ordering match what you would expect based on the alkyl group? Explain. Does this ordering match what you would expect based on leaving group? Explain. (To decide, you must compare only the three primary halides. Comparing a primary bromide with a tertiary chloride, for example, will not give a valid comparison of leaving groups as the substitution is also different.) 4. Give...

3. (8 pts) Silver nitrite is known to react with primary alkyl bromides or iodides to form the corresponding nitro compounds (RNO2). However, it reacts with secondary and tertiary halides to form the corresponding nitrite esters (RONO). What are the most likely reasons contributing to this product distribution? R-X + AgNO, — RNO or RONO R = 1° only X = Br, 1 R = 29, 30 X = Br,

Question: In the Silver Nitrate (in Ethanol)
test, what does the silver react with to produce precipitate?
Background: In Ochem lab, we are investigating
the reactivities of certain alkyl halides. I added a picture from
my lab manual that may help.
HulleUpone and enabol is a moderately powerful ionizing solvent. The silver von because of its ability to coordinate the leaving halide ion to form a silver halide pre cipitate, greatly assists the ionization of the alkyl halide. Again, a...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...

1. In both the sodium iodide
test and the silver nitrate test, why does 2-bromobutane react
faster than 2-chlorobutane?
Bromine is a better leaving group since it is a weaker base than
chlorine is.
2. a. Why does benzyl chloride react under both
SN1 and SN2 conditions?
Benzyl
chloride is a primary alkyl halide, hence reactive under SN2
conditions.
The
primary carbocation formed due to the departure of Cl- is
stabilized by the pi electrons in the benzene ring.
b. Why is...

Arrange the alkyl halides in order of reactivity (from most to least reactive) under both SN1 (silver nitrate/ethanol) and SN2 (sodium iodide/acetone) conditions: 1-bromobutane, 2-bromobutane, bromocyclohexane, 2-bromo-2-methylpropane, 1-bromoadamantane, benzyl bromide, and bromobrmzene.

28) The reaction of tert-butyl bromide, (CH,)CBr, with ethanol affords the substitution product tert-butyl ethyl ether, (CH)1COCH CH, in acidic conditions. What would happen to the rate of the reaction if the concentration of ethanol was doubled? A) The rate remains the same. B) The rate decreases by a factor of 2 C) The rate increases by a factor of 2. D) The rate increases by a factor of 4. Circle the following alkyl halide that will undergo the fastest...
