CHM1011 PASS 2022 - Week 5

I am found in a covalent bond. Who am i?

• 2 pi bonds

• 2 sigma bonds

  
  

• A sigma bond and two pi

• A sigma and a pi bond

Which of these has the highest energy level?

• ơ*(2p)

• π*(2p)

• ơ(2s)

• π(2p)

Which of these best describe valence bond theory?

• Atomic orbitals mix and form molecular orbitals which span a whole molecule

  
  

• Molecular orbitals are hybridised atomic orbitals which bond together

  
  

• Atomic orbitals hybridise on atoms and then overlap to form bonds

  
  

• • Atomic orbitals hybridised to form bonds

  
  

When working out bond order, core electrons can be ignored.

• True

• False

Who am i if my electron density changes as you rotates around the internuclear axis?

• A pi bond

• A sigma bond

• A valence bond

• • A molecular bond

  
  

How can you tell is a molecule is diamagnetic?

• If its polar

  
  

• All electrons in molecular orbital paired up

  
  

• Not all electrons in molecular orbital are paired up

  
  

• • If its non-polar

  
  

What happens as bond order increases?

• The bond gets longer and stronger

  
  

• The bond gets shorter and stronger

  
  

• The bond gets shorter and weaker

  
  

• • The bond gets longer and weaker

  
  

Where can i access extra help?

• Monash Counselling Services

  
  

• Student Academic Success

  
  

• Friends and Family

  
  

• • Helplines like Beyond Blue and Lifeline
