(a)
Interpretation:
Fischer projection has to be drawn for the given compound below and the chiral carbons has to be indicated using asterisk.
Concept Introduction:
Fischer projection is a two dimensional representation of a molecule. In Fischer projection, the chiral carbon is shown at the intersection of horizontal line and vertical lines. The vertical lines at the intersection point represent the bonds that project into the page and the horizontal lines at the intersection point represent the bonds that are projecting out of the page. An example is given below,
Chiral carbon is the one that is bonded to four different groups in a compound. Stereoisomers possess chiral carbon atoms in their structure. An example of compound containing chiral carbon is D-Glyceraldehyde. Chiral carbon in the below structure is indicated by asterisk mark.
(b)
Interpretation:
Fischer projection has to be drawn for the given compound below and the chiral carbons has to be indicated using asterisk.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Fischer projection has to be drawn for the given compound below and the chiral carbons has to be indicated using asterisk.
Concept Introduction:

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).
