The compound that is not positional isomer of ethyl ethanoate has to be identified from the given options. Concept Introduction: Functional group isomerism is the one in which the functional group of two compounds are totally different but the molecular formula of the compounds remains the same. Esters and carboxylic acids that have same number of carbon atoms and same degree of saturation can have functional group isomerism. This is a type of constitutional isomerism. Positional isomerism exist in esters when the alkyl group and acyl group carbon chain can be arranged in different ways.

Question

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).

Interpretation Introduction

Interpretation:

The compound that is not positional isomer of ethyl ethanoate has to be identified from the given options.

Concept Introduction:

Functional group isomerism is the one in which the functional group of two compounds are totally different but the molecular formula of the compounds remains the same. Esters and carboxylic acids that have same number of carbon atoms and same degree of saturation can have functional group isomerism. This is a type of constitutional isomerism.

Positional isomerism exist in esters when the alkyl group and acyl group carbon chain can be arranged in different ways.

A mixture of 0.568 M H₂O, 0.438 M Cl₂O, and 0.710 M HClO are enclosed in a vessel at 25 °C. H₂O(g) + C₁₂O(g) = 2 HOCl(g) K = 0.0900 at 25°C с Calculate the equilibrium concentrations of each gas at 25 °C. [H₂O]= [C₁₂O]= [HOCI]= M Σ M

What units (if any) does the response factor (K) have? Does the response factor (K) depend upon how the concentration is expressed (e.g. molarity, ppm, ppb, etc.)?
