A single-displacement reaction, also known as single replacement reaction or exchange reaction, is an archaic concept in chemistry. It describes the stoichiometry of some chemical reactions in which one element or ligand is replaced by atom or group. [1] [2] [3] It can be represented generically as: + +
Substitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved, whether a reactive intermediate involved in the reaction is a carbocation, a carbanion or a free radical, and whether the substrate is aliphatic or aromatic. Detailed understanding of a reaction type helps to ...
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest.
Alternatively the reaction can be carried out with lead cyanate and ammonia. [4] The actual reaction taking place is a double displacement reaction to form ammonium cyanate: Pb(OCN) 2 + 2 NH 3 + 2 H 2 O → Pb(OH) 2 + 2NH 4 (OCN) Ammonium cyanate decomposes to ammonia and cyanic acid which in turn react to produce urea: NH 4 (OCN) → NH 3 ...

A neutralization reaction is a type of double replacement reaction. A neutralization reaction occurs when an acid reacts with an equal amount of a base. This reaction usually produces a salt. One example, hydrochloric acid reacts with disodium iron tetracarbonyl to produce the iron dihydride: 2 HCl + Na 2 Fe(CO) 4 → 2 NaCl + H 2 Fe(CO) 4
President-elect Trump's adviser on government efficiency, Elon Musk, called for eliminating the Consumer Financial Protection Bureau.
These reagents are useful because, unlike related Grignard reagents and organolithium reagents, they react with organic halides to replace the halide group with an R group (the Corey–House reaction). Such displacement reactions allow for the synthesis of complex products from simple building blocks. [1] [2] Lewis acids can be used to modify ...
