Reactive base
Webacid–base reaction, a type of chemical process typified by the exchange of one or more hydrogen ions, H +, between species that may be neutral ( molecules, such as water, H 2 O; or acetic acid, CH 3 CO 2 H) or electrically charged (ions, such as ammonium, NH 4+; hydroxide, OH −; or carbonate, CO 32− ). WebJul 20, 1998 · base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis). Examples of bases are the hydroxides of the alkali and alkaline earth metals (sodium, …

WebA reactant can be a good nucleophile and a good base and act as either. Consider H O− or hydroxide. Depending on the conditions, it can act as a base and turn into water, or it can attack an electrophile in an SN 2 fashion Consider Br− which is a base and a good nucleophile, It will tend to act in an SN2 fashion Webacid–base reaction, a type of chemical process typified by the exchange of one or more hydrogen ions, H +, between species that may be neutral ( molecules, such as water, H 2 O; or acetic acid, CH 3 CO 2 H) or electrically charged (ions, such as ammonium, NH 4+; hydroxide, OH −; or carbonate, CO 32− ). It also includes analogous behaviour ...
WebEpoxide structure. Epoxides (also known as oxiranes) are three-membered ring structures in which one of the vertices is an oxygen and the other two are carbons. The carbons in an epoxide group are very reactive electrophiles, due in large part to the fact that substantial ring strain is relieved when the ring opens upon nucleophilic attack ... WebOct 27, 2024 · The most common strong bases are ionic compounds that contain the hydroxide ion as the anion; three examples are NaOH, KOH, and Ca (OH) 2. Common weak acids include HCN, H 2 S, HF, oxoacids such as HNO 2 and HClO, and carboxylic acids such as acetic acid. The ionization reaction of acetic acid is as follows:

WebAs we learnt in section 8.2, the nucleophile has no effect on the rate of an S N 1 reaction. This means that we only need to consider the electrophile, usually an alkyl halide. Another feature of the S N 1 reaction is that it is often prone to side reactions, which is why it is less used in synthesis than the S N 2 reaction..
