The reaction of 2,2-dimethyl-1-piopanol with hbr is very slow and gives 2-bromo- 2-methyibutane as the major product. give a mechanistic explanation for these observations. select all that apply. stereoelectronic effects result in an antic op lanar rearrangement of the carbon skeleton. steric hindrance prevents nucleophilic attack. the mechanism requites the development of an unstable positively charged species in the transition state. the mechanism results in a carbocation rearrangement in which a methyl shift occurs. the mechanism requires dissociation of a poor leaving group.

Correct option : "The mechanism results in a carbocation rearrangement in which a methyl shift occurs"

Explanation:

In the first step, 2,2-dimethyl-1-propanol gets protonated.

In the second step, a carbocationic intermediate is produced from removal of .

In the third step, shifting of methyl group occurs to produce more stable carbocationic intermediate.

In the fourth step, attacks the stable carbocation to produce 2-bromo-2-methylbutane.

So, correct option : "The mechanism results in a carbocation rearrangement in which a methyl shift occurs"

Full reaction mechanism has been shown below.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
