Answer:
2-iodo-2-methylpentane > 2-bromo-2-methylpentane > 2-chloro-2-methylpentane > 2-chloro-2-methylpentane
Explanation:
In this case, the<u> Sn1 reaction</u> would form a <u>carbocation</u>. So, the molecule that can generate a <u>very stable carbocation</u> will be more reactive. We have to remember that <u>tertiary carbocations</u> are the more stable ones. With this in mind, 3-chloropentane would be the <u>least reactive</u> molecules of all.
Then to decide which one is more reactive between the other ones, we have to check the <u>leaving group</u>. In this case, all the atoms are <u>halogens</u>, so if we have a <u>larger atom</u> the leaving group would leave <u>more easily</u>.
With his in mind the larger atom would be I, then Br and finally Cl, therefore the 2-iodo-2-methylpentane would be the <u>more reactive one.</u>
Gay-Lussacs law states that pressure of a gas is directly proportional to temperature when the volume is kept constant
P / T = k
where P - pressure , T - temperature in kelvin and k - constant
where parameters for the first instance are on the left side of the equation and parameters for the second instance are on the right side of the equation
T1 - 25 °C + 273 = 298 K
substituting the values in the equation
T2 = 388 K
temperature in celcius - 388 K - 273 = 115 °C
answer is C. 115 °C
A phrase that includes a verb
Explanation:
As it is given that water level is same as outside which means that theoretically, P = 756.0 torr.
So, using ideal gas equation we will calculate the number of moles as follows.
PV = nRT
or, n =
=
= 0.0052 mol
Also, No. of moles =
0.0052 mol =
mass = 0.0104 g
As some of the water over which the hydrogen gas has been collected is present in the form of water vapor. Therefore, at
= 24 mm Hg
= atm
= 0.03158 atm
Now, P =
= 0.963 atm
Hence, n =
= 0.0056 mol
So, mass of = 0.0056 mol × 2
= 0.01013 g (actual yield)
Therefore, calculate the percentage yield as follows.
Percent yield =
=
= 97.49%
Thus, we can conclude that the percent yield of hydrogen for the given reaction is 97.49%.
It would be polymer !!!!!
