I/GCSE Chemistry Question Analysis Topic: Chemistry - Short Questions
Exam Questions:
1) Identify the chiral molecule in the following pair.
2) State the Kohlrausch law of independent migration of ions. Why does the conductivity of a solution decrease with dilution?
Answers:
For I/GCSE Chemistry, you should know:
1) The chemical 2-chlorobutane has chirality. Asterisks indicate the chiral carbon atom in 2-chlorobutane.
1-chlorobutane is achiral.
The term "chiral C atom" refers to a carbon atom that is bound to four separate atoms or groups of atoms.
2) According to Kohlrausch's law of independent ion migration, an electrolyte's limiting molar conductivity can be represented by the total of the individual contributions made by its cations and anions. Because there are fewer ions available for conduction, a solution's conductivity decreases with dilution.
Work hard for your I/GCSE Chemistry examination!
End of analysis. Great!
