(a)
Interpretation:
An alcohol reactant involved in Practice Problem 12.8 as primary, secondary, or tertiary alcohol has to be classified and common name and IUPAC name for reactant and product has to be given.
Concept Introduction:
A common nomenclature of naming organic compounds has been developed by IUPAC. By usage of this nomenclature or rules, memorizing of names of organic compounds is not necessary.
IUPAC rules for naming alcohols:
- Alcohols are named by identifying the parent compound and replacing the –e ending with –ol.
Ketones are named by identifying the parent compound and replacing the –e ending with –one as suffix.- Lowest possible number should be given for the hydroxyl group present in the parent chain, similarly do for carbonyl group.
- Name and number all substituent, and put them as prefixes to “alkanol” name also give the first preference as per the alphabetical order.
- If an alcohol contains two hydroxyl groups then name it as
diol , an alcohol; contains three hydroxyl groups then name it as triol. - Common names for alcohols are derived from alkyl group corresponding to the parent compound.

- Technetium is the first element in the periodic chart that does not have any stable isotopes. Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half life ideally suited for medical tests. It would seem that the decay of technetium should fit the treatment above with the result In(c/c) = -kt. The table below includes data from the two sites: http://dailymed.nlm.nih.gov/dailymed/druginfo.cfm?id=7130 http://wiki.medpedia.com/Clinical: Neutrospec_(Technetium_(99m Tc)_fanolesomab). a. b. C. Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also graph In(c/c.) on the vertical axis versus time on the horizontal axis. When half of the original amount of starting material has hours fraction remaining disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the material to decay away). Determine the slope of your In(c/c.) vs t graph and…arrow_forwardPlease correct answer and don't use hand ratingarrow_forward1. a) Assuming that an atom of arsenic has hydrogen-like atomic orbitals, sketch the radial probability plots for 4p and 4d orbitals of S atom.
