18 Questions
In the lab assignment, students are asked to use VSEPR theory to predict and name the structure of how many molecules?
7 molecules
What is the purpose of completing Procedure A before coming to the lab according to the provided text?
To apply VSEPR theory
Which section of the lab involves drawing molecules in 3D shapes?
Analyze and Evaluate (d,e)
What does the 'Apply and Extend (g – k)' section of the lab primarily focus on?
Determining polarity
How many components are used in the lab assessment to evaluate student performance based on the provided text?
3 components
What is the total possible mark for the lab assignment according to the text provided?
46 marks
What characteristic of a molecule determines whether it is polar or non-polar?
Shape of the molecule
In the context of polarity, what does it mean when a molecule has a net dipole?
It is polar
What happens when the sum of bond dipoles in a molecule is zero?
The molecule is non-polar
How does Valence Bonding Theory explain the formation of covalent bonds?
By atomic orbital overlap with opposite-spin electrons
Which theory starts with the atom's valence orbitals to form covalent bonds?
Valence Bonding Theory
What do electron clouds represent in an atom or molecule?
Probability of finding an electron
What term is used to describe the charge separation in a covalent bond?
Bond polarity
How do you determine the type of bond between two atoms?
By calculating the electronegativity difference
What is the general trend of electronegativity values as you move across a period in the periodic table?
Increase
Which type of bond is characterized by an electronegativity difference greater than 1.7?
Ionic
What happens when a negatively charged balloon attracts the positive portion of a water molecule?
Polar behavior
In a polar covalent bond, where are the bonding electrons held closer?
One atom holds the electrons closer than the other atom
Learn about polar covalent bonds where electrons are shared unequally, resulting in a partial negative and partial positive charge on the atoms involved. Understand how bond polarity affects the chemical properties of molecules.
