Not all esters are derivatives of carboxilic acid, they could also be derivatives of phosphoric, sulphuric or carbonic (etc.) acids. However, they are called derivatives of 'X' acid because they are formed by reacting an oxoacid ('X') with a hydroxyl compound (alcohol or phenol).
See the related link and related question for more information about how esters are synthesized.
Esters are less polar than carboxylic acids, and water is a very polar solvent (like dissolves like). Furthermore, acids can ionize and form hydrogen bonds in water, etc.
because esters are derived from the reaction between alcohol and carboxiylic acids
Esters and amides are derivatives of carboxylic acids. Amines are alkylated derivatives of ammonia: carboxylic acid= R-COOH ester= R-COOR amide=R-CONH2 amine= R-NHR
Esters are generally studied as derivatives of carboxylic acids
Hydrocarbon derivatives include compounds that contain carbon and hydrogen atoms, but also other elements such as oxygen, nitrogen, halogens (fluorine, chlorine, bromine, iodine), sulfur, and phosphorus. Examples of hydrocarbon derivatives include alcohols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, amides, halogenated hydrocarbons (such as chloroform), thiols, and thioketones.
Carboxylic acids have often not very pleasant smelling. Esters smell sweeter, often fruity.
Such compounds are mostly esters.
because it is derieved from corboxylate

Because esters are alkyl derivatives of carboxylic acids so they don't have bond between O and H. as CH3-COOCH3

a carboxylic acid + an alcohol
esters are usually prepared industrially by reaction of corresponding carboxylic acid and alcohol.
Carboxylic acids have often not very pleasant smelling. Esters smell sweeter, often fruity. Structure Esters have a carboxyl group and ether linkage off the alpha carbon.
Such compounds are mostly esters.
Yes they have if they are esters of Carboxylic acids. Eg: Methyl acetate has carbonyl in its middle : H3C-(C=O)-O-CH3
No, esters are covalent compounds having polar character.
