Skeletal structural formula of three isomeric disubstituted ammonium ions that have chemical formula of C 4 H 12 N + has to be drawn. Concept Introduction: Amines are a class of organic compounds. They are derivatives of ammonia. Similar to the nitrogen atom in ammonia, the amine nitrogen also has a lone pair of electrons on it. This means that amines can act as proton acceptors. When an amine is added to water a proton is transferred to the nitrogen atom. The resulting solution is a basic solution. This contains ammonium ions and hydroxide ions. Substituted ammonium ion is the one in which one or more alkyl, aryl, or cycloalkyl groups are substituted instead of hydrogen atoms. There are two important generalizations that is applied to the substituted ammonium ion and they are, Substituted ammonium ions are not neutral molecules. They are charged species. Nitrogen atom has four bonds in ammonium ion or substituted ammonium ion. The species is positively charged as the fourth bond formed is a coordinate covalent bond.

Question

Please draw the structure in the box that is consistent with all the spectral data and alphabetically label all of the equivalent protons in the structure (Ha, Hb, Hc....) in order to assign all the proton NMR peaks. The integrations are computer generated and approximate the number of equivalent protons. Molecular formula: C13H1802 14 13 12 11 10 11 (ppm) Structure with assigned H peaks 2.08 3.13

Interpretation Introduction

Interpretation:

Skeletal structural formula of three isomeric disubstituted ammonium ions that have chemical formula of C4H12N+ has to be drawn.

Concept Introduction:

Amines are a class of organic compounds. They are derivatives of ammonia. Similar to the nitrogen atom in ammonia, the amine nitrogen also has a lone pair of electrons on it. This means that amines can act as proton acceptors. When an amine is added to water a proton is transferred to the nitrogen atom. The resulting solution is a basic solution. This contains ammonium ions and hydroxide ions.

Substituted ammonium ion is the one in which one or more alkyl, aryl, or cycloalkyl groups are substituted instead of hydrogen atoms. There are two important generalizations that is applied to the substituted ammonium ion and they are,

Substituted ammonium ions are not neutral molecules. They are charged species.

Nitrogen atom has four bonds in ammonium ion or substituted ammonium ion. The species is positively charged as the fourth bond formed is a coordinate covalent bond.
