What starting compound and what reagents should be used for most efficient synthesis of 2-bromo-1-iso-propyl-4-nitrobenzene? Eff

icient synthesis means that on each step you take the major product or one of the major products and continue reacting it with assigned reagent further. The final product is must be major product of the reaction as well.
Select one:
A. Start with iso-propylbenzene First step: HNO,+H2S04 Second step: Br2+FeBr
B. Start with bromobenzene First step: HNO,+H2SO Second step: 2-chloropropane + AIC
C. Start with nitrobenzene First step: 2-chloropropane +AICI Second step: Br,+FeBr

Answer:

A

Explanation:

Alkyl substituents on benzene are ortho, para directing. They activate the benzene ring towards electrophilic substitution at the 2 and 4 positions. Nitration is an electrophilic addition to the benzene ring and will occur at the 2 and 4 positions. The para nitro product predominates due to steric effects. Bromine, being smaller than -NO2 can be directed to the ortho position. Hence te compound is formed

I'm looking at the barometer in my lab as I type this question. It says the pressure is 968 torr. What is this pressure expresse
Ksenya-84 [330]

Answer:

1.27 atm.

Explanation:

The following data were obtained from the question:

Pressure (P) in torr = 968 torr

Pressure (P) in atm =...?

Thus, we can convert from torr to atm by doing the following:

Recall:

760 torr = 1 atm

Therefore,

968 torr = 968/760 = 1.27 atm

Therefore, 968 torr is equivalent to 1.27 atm.

Which aldehyde is an intermediate in the reduction of ethyl benzoate with lithium aluminum hydride?
garri49 [273]

Answer:

tetrahedral aldehyde

Explanation:

  1. The reaction begins with a hydride nucleophile reacting with the ester carbonyl carbon to form the tetrahedral intermediate.
  1. The carbonyl reforms to produce an aldehyde with the loss of the alkoxide ion.
  2. The resulting aldehyde undergoes a subsequent reaction with a hydride nucleophile to form another tetrahedral intermediate. The carbonyl is not able to reform, because there are no stable leaving groups.
  3. Therefore, the tetrahedral intermediate is protonated to produce a primary alcohol.
