isopentyl alcohol polarity definition

Octyl acetate

Isoamyl acetate also known as isopentyl acetate is an organic compound that is the ester formed from isoamyl alcohol and acetic acid It is a colorless liquid that is only slightly soluble in water but very soluble in most organic solvents Isoamyl acetate has a strong odor which is also described as similar to both banana and pear

Synthesis of Esters Essay

Definition Esters are chemical compounds consisting of a carbonyl adjacent to an ether linkage They are derived by reacting an oxo acid with a hydroxyl compound such as an alcohol or phenol Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group and most commonly from carboxylic acids and alcohols
