Chapter 23, Problem 63A

Interpretation Introduction

Interpretation: To draw the structures of Cadaverine and Putrescine.

Concept Introduction: The structural formula is used to represent the atoms of a chemical compound. It is the way of representing the chemical compound and chemical proportions of an atom using symbols of elements. It is also used to show the molecular arrangement of atoms.

Answer to Problem 63A

  

Explanation of Solution

In Cadaverine which is 1,5-pentanediamine the longest carbon chain contains five carbon atoms and the amine group is attached to the first and the fifth carbon. Similarly, in Putrescine which is 1,4-butanediamine the longest carbon chain contains four carbon atoms and the amine group is attached to the first and the fourth carbon.

Conclusion

The condensed structural formula shows the representation of the atoms in the chemical compound. Therefore, the structural formula is given based on the longest carbon chain and the position of the functional groups.
