(a)
Interpretation:
The correct formula for barium oxide is to be determined.
Concept introduction:
The general rules for naming ionic compounds are:
1) The cation or metal is named first followed by the name of the anion or nonmetal for naming all ionic compounds.
2) For binary ionic compounds, the cation name is the same as that of the metal whereas the anion name has the suffix
(b)
Interpretation:
The correct formula for
Concept introduction:
The general rules for naming oxoanion compounds are:
1) The ion with the most number of oxygen atoms has the
2) The one with one less oxygen atom does not have the
3) The ion with two fewer oxygen atoms has just the root and the suffix
4) The ion with three fewer oxygen atoms has the prefix
(c)

- 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
