WitrynaThe Hydroboration Oxidation reaction is an organic chemical reaction which is employed for the conversion of alkenes into alcohols that are neutral. This is done via a two-step process which includes a hydroboration step and an oxidation step. This is done by a net addition (across the entire double bond) of water. WitrynaA double replacement reaction is specifically classified as a precipitation reaction when the chemical equation in question occurs in aqueous solution and one of the of the products formed is insoluble. An example of a precipitation reaction is given below: (1) C d S O 4 ( a q) + K 2 S ( a q) → C d S ( s) + K 2 S O 4 ( a q) Both reactants are ...
