Complete answer: Some chemical reaction of aldehydes and ketones are: i - Addition of hydrogen cyanide: Acetaldehyde in reaction with hydrogen cyanide gives acetaldehyde cyanohydrins. The reaction is: Acetone in reaction with hydrogen cyanide gives acetone cyanohydrins.
The reaction is: ii - Addition of Grignard reagent: Formaldehyde when reacted with Grignard reagent produces primary alcohol. The reaction is given below: Acetaldehyde when reacts with Grignard reagent, it produces secondary alcohol.
The reaction is given below: Acetone when reacts with Grignard reagent, it produces tertiary alcohol. The reactions are given below: vi - Halogenation reaction: Aldehydes and ketones also give halogenations reaction as given below: vii - Reaction with alkalis: Aldehydes and ketones in the presence of dilute sodium hydroxide give aldols. These reactions are given below: Note: The reaction of aldehydes and ketones with alkalies is known as an aldol condensation reaction. Aldehydes and ketones show so many chemical reactions because they are very reactive.

Embed Size px x x x x From the standpoint of the organic component, an oxidation can involve the removal of hydrogen atoms OR the addition of oxygen to the structure. Oxidation of AldehydesOxidation of Aldehydes forms the basis of two useful identification tests. In some cases, the identity of A and B and the groups attached to the double bond influence the orientation of the addition. The identity of A and B and the polar nature of the carbon-oxygen double bond influence the orientation of the addition.
Physical properties of acids and acid derivatives :. Boiling point :. The high boiling points of carboxylic acids is the result of formation of a stable hydrogen-bonded dimer. Hydrogen bonded acid dimer. Carboxylic acids form hydrogen bonds with water and the lower molecular —weight carboxylic acids upto 4 carbon atoms are miscible with water. Acid derivatives esters, acid chlorides, anhydride, nitriles and amides are soluble in organic solvents such as alcohols, ethers, chlorinated alkanes and aromatic hydrocarbons. Methods of preparation of carboxylic acids:.

Properties of Aldehydes and Ketones
The boiling point of aldehydes and ketones is higher than that of non-polar compounds hydrocarbons but lower than those of corresponding alcohols and carboxylic acids as aldehydes and ketones do not form H-bonds with themselves. The lower members up to 4 carbons of aldehydes and ketones are soluble in water due to H-bonding. The higher members do not dissolve in water because the hydrocarbon part is larger and resists the formation of hydrogen bonds with water molecules.
The only structural difference between hydrocarbons and aldehydes is the presence in the latter of the carbonyl group , and it is this group that is responsible for the differences in properties, both physical and chemical. This gives the oxygen a partial negative charge and the carbon a partial positive charge. The negative end of one polar molecule is attracted to the positive end of another polar molecule, which may be a molecule either of the same substance or of a different substance. The polarity of the carbonyl group notably affects the physical properties of melting point and boiling point , solubility, and dipole moment. Hydrocarbons, compounds consisting of only the elements hydrogen and carbon, are essentially nonpolar and thus have low melting and boiling points.
The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde. If neither is hydrogen, the compound is a ketone.
Acetaldehyde is an extremely volatile, colorless liquid. The higher members do not dissolve in water because the hydrocarbon part is larger and resists the formation of hydrogen bonds with water molecules. The oxygen atom of the carbonyl group engages in hydrogen bonding with a water molecule. Table
В голосе Беккера слышались извиняющиеся нотки: - Простите, но это определенно осмысленные слова. Они выгравированы очень близко одно к другому и на первый взгляд кажутся произвольным набором букв, но если присмотреться повнимательнее, то… становится ясно, что надпись сделана по-латыни.
