Chemistry Quiz Regarding Hybridized Orbital Shapes - Quiz

In chemistry, orbital hybridisation is the concept of mixing atomic orbitals into new hybrid orbital. You can find the hybridization of an atom by finding its steric number. Did you understand all we learnt about the topic? Please answer the following questions regarding hybridized orbital shapes to the best of your ability and get to see just how much you know about the topic.

Questions and Answers

1.

1. What is the molecular shape of BI₃?
- A.
  
  Tetrahedral
- B.
  
  Trigonal pyramidal
- C.
  
  Linear
- D.
  
  Trigonal planar
- E.
  
  Octahedral
Correct Answer
D. Trigonal planar

Explanation
The correct answer is trigonal planar. In the molecule BI3, there are three bonding pairs of electrons and no lone pairs on the central atom. This arrangement gives rise to a trigonal planar molecular shape, where the three bonding pairs are spread out in a flat triangle around the central atom. The bond angles in a trigonal planar molecule are approximately 120 degrees.

2. What is the electron geometry of NF₃?
- A.
  
  Tetrahedral
- B.
  
  Trigonal pyramidal
- C.
  
  Linear
- D.
  
  Trigonal planar
- E.
  
  Octahedral
Correct Answer
A. Tetrahedral

Explanation
The electron geometry of NF3 is tetrahedral. This means that the central nitrogen atom is surrounded by four electron pairs, including three bonding pairs and one lone pair. The presence of the lone pair causes the molecule to have a trigonal pyramidal molecular geometry.

3. What is the molecular shape of C₂H2?
- A.
  
  Tetrahedral
- B.
  
  Trigonal pyramidal
- C.
  
  Linear
- D.
  
  Trigonal planar
- E.
  
  Octahedral
Correct Answer
C. Linear

Explanation
The molecular shape of C2H2 is linear because it consists of two carbon atoms bonded together with a triple bond. The triple bond consists of one sigma bond and two pi bonds, which results in a linear arrangement of the atoms.

4. What is the molecular shape of SCl₆?
- A.
  
  Tetrahedral
- B.
  
  Trigonal pyramidal
- C.
  
  Linear
- D.
  
  Trigonal planar
- E.
  
  Octahedral
Correct Answer
E. Octahedral

Explanation
The correct answer is Octahedral. Octahedral refers to a molecular shape in which there are six electron groups surrounding the central atom. In the case of SCl6, sulfur (S) is the central atom and it is bonded to six chlorine (Cl) atoms. The molecule has a symmetrical arrangement with the sulfur atom at the center and the six chlorine atoms surrounding it, creating an octahedral shape.

5. What are the bond angles of SCl₆?
- A.
  
  180 deg
- B.
  
  90 deg/ 120 deg
- C.
  
  109.5 deg
- D.
  
  90 deg
- E.
  
  120 deg
Correct Answer
D. 90 deg

Explanation
The correct answer is 90 deg. This is because SCl6 has an octahedral molecular geometry, meaning it has six bonding pairs and no lone pairs of electrons around the central sulfur atom. In an octahedral geometry, the bond angles between the bonding pairs are all equal and measure 90 degrees.
