(a) Interpretation: The hemiacetal which is formed when benzaldehyde (C 6 H 5 CHO) is treated with one equivalent of cyclohexanol should be determined. Concept introduction: Alcohol and ether groups are bound to the same carbon in a hemiacetal. A hemiacetal is resulted as an intermediate of the formation of acetal during the reaction between alcohol and aldehyde . Bezaldehyde is a cyclic aldehyde and cyclohexanol is a cyclic alcohol.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

(a)

Interpretation:

The hemiacetal which is formed when benzaldehyde (C₆H₅CHO) is treated with one equivalent of cyclohexanol should be determined.

Concept introduction:

Alcohol and ether groups are bound to the same carbon in a hemiacetal. A hemiacetal is resulted as an intermediate of the formation of acetal during the reaction between alcohol and aldehyde. Bezaldehyde is a cyclic aldehyde and cyclohexanol is a cyclic alcohol.

Interpretation Introduction

(b)

Interpretation:

The acetal which is formed when benzaldehyde is reacted with two equivalents of cyclohexanol in the presence of H₂SO₄ should be determined.

Concept introduction:

When an aldehyde or a ketone is reacted with two equivalent alcohol molecules in the presence of H₂SO₄, an acetal is produced. In acetal formation, two alkoxy groups are bonded to the same carbon.

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).

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.)?
