Interpretation:
To draw the structural formula for the compound.
Concept Introduction:
Structural formula is the spatial arrangement of atoms of a molecule in space.
In the condensed formula is a line-angle formula, the symbol for carbon and hydrogen atoms are not shown. Only carbon-carbon bonds are shown using lines. Single bonds are shown as double bond as
and triple bond as
. The carbon atoms are represented as vertices and end of lines.

- When two solutions, one of 0.1 M KCl (I) and the other of 0.1 M MCl (II), are brought into contact by a membrane. The cation M cannot cross the membrane. At equilibrium, x moles of K+ will have passed from solution (I) to (II). To maintain the neutrality of the two solutions, x moles of Cl- will also have to pass from I to II.
