Concept explainers
(a)
Interpretation:
Formula of magnesium nitrite has to be written.
Concept Introduction:
Ionic compounds are electrically neutral. This is because there are equal numbers of opposite charges present in the ionic compounds. Empirical formula gives a relative number of atoms of each type of element that is present in the compound to the smallest possible whole-number as subscript. If two moles of polyatomic ions are present, then the polyatomic ion is represented in parenthesis.
(b)
Interpretation:
Formula of lithium phosphate has to be written.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Formula of barium cyanide has to be written.
Concept Introduction:
Refer part (a).
(d)
Interpretation:
Formula of ammonium sulfate has to be written.
Concept Introduction:
Refer part (a).

- Q5: Label each chiral carbon in the following molecules as R or S. Make sure the stereocenter to which each of your R/S assignments belong is perfectly clear to the grader. (8pts) R OCH 3 CI H S 2pts for each R/S HO R H !!! I OH CI HN CI R Harrow_forwardCalculate the proton and carbon chemical shifts for this structurearrow_forwardA. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
