Chapter 15, Problem 45UTC
(a)
Interpretation Introduction
Interpretation:
To assign the oxidation number for each of the elements present in the given compound.
Concept Introduction :
Oxidation number or oxidation state of an atom in a molecule is the positive or the negative charge that an atom would have possessed if the compound would have been ionic. There are many rules for assigning the oxidation state to the given atom in a molecule. Some of them are:
- The oxidation state of Group 1 elements is taken to be +1.
- The oxidation state of Group 2 elements is taken to be +2.
- The oxidation state of oxygen is always -2 in most of the compounds except peroxides.
- Oxidation state of halogens is taken to be -1 usually.
- The oxidation state of hydrogen is taken to be -1 when bonded to metals and +1 when bonded to non-metals.
- Any element when present in its elemental form has zero oxidation state.
- The oxidation state of Fluorine is taken to be -1 except when present in elemental state (F2).
- The sum of oxidation states of all the atoms present in a given molecule is equal to zero.
- In case of ions, the sum of oxidation state is equal to the total charge carried by the polyatomic ion.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there
are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from
the arrow.
• Is the student's transformation possible? If not, check the box under the drawing area.
. If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts,
inorganic reagents, or other important reaction conditions above and below the arrow.
• You do not need to balance the reaction, but be sure every important organic reactant or product is shown.
