Condensed structural formula for ketone and an ester, each containing four carbon atoms has to be written. Concept Introduction: Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word. Prefix represents the substituent present in the molecule and its position in the root name. Suffix denotes the presence of functional group if any in the molecule. It can be an alkene , alkyne , alcohol, carboxylic acid , alcohol etc. Root word represents the longest continuous carbon skeleton of the organic molecule. The structure of a molecule can be drawn by analyzing the presence of prefix, suffix and root word in the given IUPAC name. Condensed structural formula is representation of the organic compound. In this the lengthy carbon chain is shown only with the carbon atoms (along with the hydrogen) without any bonds. The additional branches are shown with explicit bonds. To Write: The condensed structural formula for a ketone and an ester, each containing four carbon atoms.

Interpretation Introduction

Interpretation:

Condensed structural formula for ketone and an ester, each containing four carbon atoms has to be written.

Concept Introduction:

Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word.

Prefix represents the substituent present in the molecule and its position in the root name.

Suffix denotes the presence of functional group if any in the molecule. It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc.

Root word represents the longest continuous carbon skeleton of the organic molecule.

The structure of a molecule can be drawn by analyzing the presence of prefix, suffix and root word in the given IUPAC name.

Condensed structural formula is representation of the organic compound. In this the lengthy carbon chain is shown only with the carbon atoms (along with the hydrogen) without any bonds. The additional branches are shown with explicit bonds.

To Write: The condensed structural formula for a ketone and an ester, each containing four carbon atoms.
