Carboxylic Acid Reactivity

Sodium borohydride NaBH 4 does not reduce carboxylic acids however hydrogen gas is liberated and salts of the acid are formed Partial reduction of carboxylic acids directly to aldehydes is not possible but such conversions have been achieved in two steps by way of certain carboxyl derivatives These will be described later 2 Oxidation

Reactions of Alcohols Chemistry tutorial

Reactions of Alcohols Chemistry tutorial Introduction: Alcohols are neutral to litmus They experience diverse reactions based on the position of cleavage of the bond RO-H or R-OH making an alkoxide ion or making a carbonium ion correspondingly Acidity of Alcohols: Alcohols have no effect on the pH paper or sodium hydroxide

Topic: Metal Reactivity Halogens Archives

The order of reactivity can be determined by adding acid to different metals and observing the rate of reaction For example when hydrochloric acid is added to iron (Fe) then bubbles of hydrogen are produced slowly However if the same acid is added to zinc (Zn) then bubbles will be produced more quickly This tells us that zinc is more
