Answer:

The answer to your question is: b) Chemical property

Explanation:

Physical property: is when matter changes is physical state but it does not change its composition. For example, evaporation, condensation, sublimation, solidification, etc.

Chemical property, is when matter changes its composition because the reactants forms products.

In this question we have:

Mg + HCl ⇒ MgCl₂ + H₂↑

In this reaction, there are Mg and HCl, and after the reaction MgCl₂ and H₂ so, there was a change, and this reaction is a chemical change.

Identify the intermediate leads to the major product for the reaction of 2-methyl-2-butene with hydrogen bromide in the presence

pishuonlain [190]

Answer:

Explanation:

We must have a good idea of the fact that there are two mechanisms that come into play when we are discussing about the addition of hydrogen halides to alkenes. The first is the ionic mechanism and the second is the radical mechanism.

The ionic mechanism is accounted for by the Markovnikov rule while the radical mechanism occurs in the presence of peroxides and is generally referred to as anti Markovnikov addition.

The intermediate in anti Markovnikov addition involves the most stable radical, in this case, it is a tertiary radical as shown in the images attached. The most stable radical is II hence it leads to the major product shown in the other image.
