Because esters are alkyl derivatives of carboxylic acids so they don't have bond between O and H. as CH3-COOCH3
The minimum number of oxygen atoms present in an ester molecule is one. This oxygen atom is typically part of the carbonyl group within the ester functional group.
X-OH + HOOC-Y = X-O-CO-Y + H2O alcohol + acid = ester + water so -O-CO- is an ester
The minimum number of hydrogen atoms present in a carboxylic ester is two: one hydrogen atom attached to the oxygen in the ester functional group and one hydrogen atom on the carbon atom adjacent to the ester group.
The type of bond present in the nucleotide that involves the selection of the phosphate ester (phosphoester) bond is a covalent bond.
Stretches.
According to the answer of a recent assignment, the functional groups are cis and trans alkenes, ester and ketone.
The primary bond present in lipids is the ester bond. It connects the fatty acids to the glycerol backbone in triglycerides, phospholipids, and glycolipids.
The product formed when benzoic acid reacts with ethanol is ethyl benzoate, along with water. This reaction is an esterification process, where the -OH group of the benzoic acid reacts with the -OH group of ethanol to form the ester and water as a byproduct.
Alcohols donate hydrogen because they are nucleophiles, capable of donating a pair of electrons to form a bond. Carboxylic acids donate the OH group as it is a leaving group, facilitating the elimination of water in ester formation. This process involves the nucleophilic attack of the alcohol on the carbonyl carbon of the carboxylic acid, leading to the formation of an ester and water as a byproduct.

No. There is not an ester.
Zani Ester goes by Ester.
