Chapter 15, Problem 15.57E

Interpretation Introduction

(a)

Interpretation:

The structure for monoethyl phosphate (with a $2^{-}$ charge) is to be drawn.

Concept introduction:

Ethyl dihydrogen phosphate is the other name of the monoethyl phosphate. It belongs to the organophosphates. They are formed by the ester of phosphoric acid and the corresponding alcohol. The molecular formula of monoethyl phosphate is ${\left({\text{C}}_2{\text{H}}_5{\text{O}}_{\text{4}}\text{P}\right)}^{2-}$.

Interpretation Introduction

(b)

Interpretation:

The structure for monoethyl diphosphate (with a $3^{-}$ charge) is to be drawn.

Concept introduction:

The monoethyl diphosphate belongs to the organophosphates. They are formed by the ester of phosphoric acid and the corresponding alcohol. The molecular formula of monoethyl diphosphate is ${\left({\text{C}}_2{\text{H}}_5{\text{P}}_2{\text{O}}_7\right)}^{3-}$.

Interpretation Introduction

(c)

Interpretation:

The structure for monoethyl triphosphate (with a $4^{-}$ charge) is to be drawn.

Concept introduction:

The monoethyl triphosphate belongs to the organophosphates. They are formed by the ester of phosphoric acid and the corresponding alcohol. The molecular formula of monoethyl triphosphate is ${\left({\text{C}}_2{\text{H}}_5{\text{P}}_3{\text{O}}_{10}\right)}^{4-}$.
