Magnesium carbonate, Mg CO3 (archaic name magnesia alba), is an inorganic salt that is a white solid.Several hydrated and basic forms of magnesium carbonate also exist as minerals.orms [edit]. The most common magnesium carbonate forms are the anhydrous salt called magnesite (MgCO 3) and the di, tri, and pentahydrates known as barringtonite (MgCO 3 Â·2 H 2 O), nesquehonite (MgCO 3 Â·3 H 2 O), and lansfordite (MgCO 3 Â·5 H 2 O), respectively.
Reaction type: Nucleophilic Substitution (SN1 or SN2). Summary: 1  When treated with HBr or HCl alcohols typically undergo a nucleophilic substitution reaction to generate an alkyl halide and water.eaction of Alcohols with other Halogenating agents (SOCl2, PX3). Reaction type: Nucleophilic Substitution (SN1 or SN2). Summary: 1  Alcohols can also be converted to alkyl chlorides using thionyl chloride, SOCl2, or phosphorous trichloride, PCl3.
Primary alcohols can be oxidised to either aldehydes or carboxylic acids depending on the reaction conditions. In the case of the formation of carboxylic acids, the alcohol is first oxidised to an aldehyde which is then oxidised further to the acid. Partial oxidation to aldehydes. You get an aldehyde if you use an excess of the alcohol, and distil off the aldehyde as soon as it forms.
