Discover nucleophilic addition reactions of aldehydes and ketones and see examples. Understand the reactivity of carbonyl compounds to undergo nucleophilic substitutions. Related to this Question What is the molality of a solution composed of 192 g of acetone ((CH_3)_2CO) dissolved in 416 ...
Under the generic name "algeldrate", aluminium hydroxide is used as an antacid in humans and animals (mainly cats and dogs). It is preferred over other alternatives such as sodium bicarbonate because Al(OH)3, being insoluble, does not increase the pH of stomach above 7 and hence, does no...

What is thermite process and its uses? Thermite process : When highly reactive metals such as Sodium, Calcium, Aluminium etc., are usedas reducing agents they displace metals of lower reactivity from thecom-pound. These are exothermic reactions. The amount of heat evolved is so large that the...
A chloride ion, with its extra electron, typically forms ionic bonds, especially with metals, leading to common compounds like sodium chloride (table salt). 7 The reactivity of a chlorine atom is higher due to its desire to achieve a stable electron configuration by gaining an electron. The ...
The increase in reactivity correlates to a decrease inelectronegativity(increase in electropositivity.) So, just by looking at theperiodic table,you can predict lithium will be less reactive than sodium, and francium will be more reactive than cesium and all of the other elements listed above it ...
