Answer:
(3S)-2-chloro-2,3-dimethylpentane is produced exclusively.
Explanation:
Electrophilic addition to (3S)-2,3-dimethylpent-1-ene proceeds through a carbocationic intermediate.
In the first step, adds onto double bond to produce more stable tertiary carbocation. (protonation)
In the second step, adds onto carbocation to produce (3S)-2-chloro-2,3-dimethylpentane exclusively.(nucleophilic addition)
So, option (d) is correct.
Explanation:
It is known that for , ppm present in 1
are as follows.
1 = 0.494 ppm
So, 150 =
= 0.15
Therefore, calculate the equivalent concentration in ppm as follows.
= 0.074 ppm
Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
Explanation:
The given data is as follows.
Vapour pressure of pure = 33.85 Torr
Temperature = 298 K
Mole fraction of = 122.36 torr
Therefore, calculate the vapor pressure of as follows.
Vapour pressure of = mole fraction of
x K of
= 0.050 x 122.36 Torr
= 6.118 Torr
So, vapor pressure of is 6.118 Torr
.
Now, calculate the vapor pressure of carbon tetrachloride as follows.
Vapour pressure of = mole fraction of
x Pressure of
= (1 - 0.050) × 33.85 Torr
= 32.1575 Torr
So, vapor pressure of is 32.1575 Torr .
Hence, the total pressure will be as follows.
= 6.118 Torr + 32.1575 Torr
= 38.2755 Torr
Therefore, composition of =
= 0.8405
Composition of is 0.8405
.
And, composition of =
= 0.1598
Composition of is 0.1598
.
