Write a mechanism for the formation of triphenylmethanol from the reaction of phenylmagnesium bromide and diethyl carbonate..

Chemistry

My name is Ann [436]1 year ago

The reaction  proceeds through nucleophilic acyl substitution reaction.

Phenyl magnesium bromide substitutes one ethoxide ion in the nucleophilic acyl substitution reaction that drives the process forward. A subsequent equivalent of phenyl magnesium bromide produces triphenyl methanol through a nucleophilic addition reaction with the resultant keto group.

There are two ethoxy leaving groups in diethyl carbonate. Tertiary alcohol is created when diethyl carbonate combines with too much Grignard reagent. The Grignard reagent attacks the carbonyl carbon three times in the mechanism to produce the tertiary alcohol.

The mechanism is shown below:

I need help with with number 1515. How many moles of NO2 are in a 37.058 L container at 101.28 kPa and -139.86
Andre45 [30]

Explanation:

To solve this question, we will use the Clayperon Equation:

P.V = n.R.T

where:

P = 101.28 kPa

1 atm = 101,325 Pa

x atm = 101,280 Pa

x = 1 atm

V = 37.058 L

n = we don't know

R = 0.082 atm.L/K.mol

T = -139.88 ºC = -139.88+273.15 = 133.27 K

1*37.058 = n*0.082*133.27

n = 0.29 moles

Answer: 0.29 moles

Type the temperatures in Kelvin) in the left column
docker41 [41]

Answer: the data appear to be ( linear )

The line of best fit is v= 0.003 t+ 0.003

Notice the the value of the v intercept is close to 0 so V and t are ( directly proportional)

what is the molarity of a RbOH solution if 60.0 mL of the solution is neutralized by 52.8 mL of a 0.5M HCl solution (Hint: Ma x
Dahasolnce [82]
RbOH is a strong base that dissociates completely and HCl is a strong acid that too dissociates completely. the complete reaction between the acid and base is;
RbOH + HCl ---> RbCl + H₂O
stoichiometry of acid to base is 1:1
At neutralisation point
H⁺ mol = OH⁻ mol
mol = molarity x volume 
if Ma - molarity of acid and Va - volume of acid reacted
Mb - molarity of base and Vb - volume of base reacted 
Ma x Va = Mb x Vb
0.5 M x 52.8 mL = Mb x 60.0 mL 
Mb = 0.44 M 
molarity of base - 0.44 M
