The gabriel amine synthesis is a method for preparing a primary amine from an alkyl halide. the reaction involves the alkylation of phthalimide. in phthalimide, the n-h hydrogen is acidic due to the two flanking carbonyl groups. thus, phthalimide can be deprotonated by a strong base. the resulting anion is a strong nucleophile and readily displaces halide in an sn2 reaction, leading to an n-alkylated imide. the imide is then hydrolyzed in aqueous base to yield the primary amine and phthalate. draw curved arrows to show the movement of electrons in this step of the mechanism

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).
