The most stable ion for the given elements is to be predicted; the given atoms are to be arranged in the decreasing order of the radius and the variation observed in the radius is to be explained. Concept introduction: The measure of the size of the atoms present in a chemical element is known as its atomic radius. The atomic radius, in the periodic table, decreases while going from left to right in a period and increases while going from top to bottom in a group. To determine: The most stable ion that can be formed for the given elements; the correct order of elements arranged according to the decrease in the atomic radius and the reason that leads to this variation in the atomic radius.

How many signals do you expect in the H NMR spectrum for this molecule?
Br
Br
Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red.
Note for advanced students: In this question, any multiplet is counted as one signal.
Number of signals in the 'H NMR spectrum.
For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to
the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in top
molecule
For the molecule in the bottom drawing area, highlight in red any other H atoms that will
contribute to the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in bottom
molecule
In the drawing area below, draw the major products of this organic reaction:
1. NaOH
?
2. CH3Br
If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area
instead.
No reaction.
