Chapter 23, Problem 66A

Interpretation Introduction

Interpretation: To draw the structural formula for Tetra-hydro furan.

Concept Introduction: Structural Formula will give a brief picture of atoms or molecules in the order they are bonded. It also represents how the atoms are bonded to one another via a single bond, double bond, or triple bond. In the structural formula, the covalent bonds are represented by a dash.

Answer to Problem 66A

  

Explanation of Solution

From the structure, it is clear that Tetrahydro furan is a heterocyclic compound because there is a heteroatom oxygen present in place of carbon. It is a cyclic ether with a molecular formula ${{\text{(CH}}_{\text{2}}\text{)}}_{\text{4}}\text{O}$ . A five-membered ring with oxygen is called a furan ring therefore, it is named Tetrahydrofuran. Tetrahydrofuran is a polar molecule.

Conclusion

In the structural formula of tetrahydrofuran the carbons, hydrogen, and oxygen are represented by a covalent bond. Since it is in the form ${\text{R-O-R}}^{\text{'}}$ it is considered ether and as the atoms are arranged in a cyclic ring it is called cyclic ether.
