Most stable conformer should be found between the given two chair conformations. Concept introduction: Chair conformer: chair conformer is a stable conformer for cyclohexane compound. In this chair conformer two positions are important for substitutions one is equatorial and other one axial position. Axial positions are parallel to the axis of ring while equatorial positions are perpendicular to the axis of the ring. Example: Newman projection: Newman projection of molecule is one type of representations for the alkanes , where the projection visualization from one carbon to another carbon. In this Newman projection, front carbon which represented with dot is called proximal and the back carbon which represented with circle is called distal. The most stable conformation in the Newman projection is the one which has least steric hindrance among all conformations.

(a)

Interpretation Introduction

Interpretation:

Most stable conformer should be found between the given two chair conformations.

Concept introduction:

Chair conformer: chair conformer is a stable conformer for cyclohexane compound. In this chair conformer two positions are important for substitutions one is equatorial and other one axial position. Axial positions are parallel to the axis of ring while equatorial positions are perpendicular to the axis of the ring.
Example:

Newman projection: Newman projection of molecule is one type of representations for the alkanes, where the projection visualization from one carbon to another carbon. In this Newman projection, front carbon which represented with dot is called proximal and the back carbon which represented with circle is called distal.

The most stable conformation in the Newman projection is the one which has least steric hindrance among all conformations.

Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…
