Interpretation:
The group number designated in European convention as Group
Concept introduction:
The periodic table represents elements in order of their increasing
(b)
Interpretation:
The group number designated in European convention as Group
Concept introduction:
The periodic table represents elements in order of their increasing atomic numbers. In the modern periodic table, the horizontal rows are known as periods, and the vertical columns are known as groups. There are seven periods and eighteenth groups in the modern periodic table.

- A student wants to make the following product in good yield from a single transformation step, starting from benzene. Add any organic reagents the student is missing on the left-hand side of the arrow, and any addition reagents that are necessary above or below the arrow. If this product can't be made in good yield with a single transformation step, check the box below the drawing area.
