Answer:
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.

Answer:
Cohesion
Explanation:
Cohesion tension theory of water movement up the tree vessels
Cohesion is the term used to describe the binding forces present in water molecules through hydrogen bonds as such the water molecules have considerable tensile strenghth allowing them to be pulled up into the leaves of plants through the tree vessels without breakage as longitutudinal stress are placed on the water as it is pulled up
Answer:
Topographical
Explanation:
When it comes to questions such as this one, the thing that could help you the most is a dictionary. A dictionary is an alphabetically arranged listing of words that contains various information about those words, such as their definitions, examples, origin, pronunciation, etc.
The term the given definition refers to is <em>topographical</em>. Topography is the study of the forms and features of land surfaces. The topography of an area refers to its physical properties and terrain or their description (e.g. how they're shown on a map).
