Consider the acid-catalyzed hydration of 3-methyl-1-butene. for each of the four steps, add one or two curved arrows to the reactant side to show the mechanism.

This addition follows MarkowniKov's rule

Explanation:

The image attached shows the mechanism of the reaction. It can easily be seen that a secondary carbocation is formed leading to the alkanol. The image simplifies the mechanism which involves the initial addition of the hydroxide followed by the hydrogen ion.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
