What is HCOOCH CH2 H2O?

HCOOCH CH2 H2O represents the chemical structure of ethyl glycolate, which is an ester formed by the reaction between glycolic acid and ethanol. This organic compound is part of the broader family of esters, compounds that are typically characterized by the presence of a functional group known as -COO (carbonyl group bonded to an oxygen atom).

The structure of ethyl glycolate can be broken down as follows:

  • HCO refers to the formyl group, derived from glycolic acid, an α-hydroxy acid that plays a role in various biological processes.
  • OCH₂CH₂OH is the ethoxy group (from ethanol), where CH₂CH₂OH refers to an ethyl group (C₂H₅) bonded to a hydroxyl group (-OH), commonly known as ethanol.

Ethyl glycolate is a colorless, volatile liquid with a mildly fruity odor. As an ester, it inherits some of the characteristic properties of esters, such as its ability to dissolve in organic solvents and its relatively low boiling point.

Molecular Composition of HCOOCH CH2 H2O

Ethyl glycolate, with the formula HCOOCH CH2 H2O, is a small organic molecule that contains:

  • C₂H₄O₂ (Ethyl glycolate): This is the parent structure, consisting of a glycolic acid molecule bonded with an ethanol molecule via an ester bond.
  • Functional Groups:
    • The carbonyl group (-COO) connects the glycolic acid portion to the ethanol group.
    • The hydroxyl group (-OH) is part of the ethanol structure, and it contributes to the molecule’s ability to participate in various chemical reactions.
