EXAM 1
September 7, 2022
Be sure to read each question carefully. Partial credit may be assigned where warranted. Only answers
written in the boxes or on the lines will be graded. You must write your name and myID on pages 1,3,
and 5 or two points will be deducted from your exam total for each omission. No student ID = -2 points.
1. (6 points) Darken the bubble to select the correct hybridization for each indicated atom.
2. (6 points) Darken the bubble to select the correct formal charge for each indicated atom.
3. (6 points) Consider the skeletal structure shown and answer the associated questions.
I. Provide the molecular formula for the molecule represented above.
II. How many total sigma bonds are present in the molecule represented above?
III. How many total pi bonds are present in the molecule represented above?
There are 109 points available on this exam
and 11 problems (some with multiple parts).
Manage your time carefully and
consciously.

EXAM 1

September 7, 2022 Be sure to read each question carefully. Partial credit may be assigned where warranted. Only answers written in the boxes or on the lines will be graded. You must write your name and myID on pages 1,3, and 5 or two points will be deducted from your exam total for each omission. No student ID = - 2 points.

  1. (6 points) Darken the bubble to select the correct hybridization for each indicated atom.
  2. (6 points) Darken the bubble to select the correct formal charge for each indicated atom.
  3. (6 points) Consider the skeletal structure shown and answer the associated questions. I. Provide the molecular formula for the molecule represented above. II. How many total sigma bonds are present in the molecule represented above? III. How many total pi bonds are present in the molecule represented above? There are 1 09 points available on this exam and 1 1 problems (some with multiple parts). Manage your time carefully and consciously.
  1. (8 points) For each of the following acid pairs, indicate the stronger acid by darkening in the appropriate bubble located underneath your choice. Also, in the box provided, write the letter for the stabilization factor that best supports the difference in acidity. A. Electronegativity B. Size C. Hybridization D. Inductive electron withdrawal E. Inductive electron withdrawal + proximity F. Resonance (a.k.a. electron delocalization)
  2. (10 points) For each of the following Bronsted-Lowry acid/base reactions: I. Provide skeletal structures for the products that would form if the reaction proceeds as written. All atoms must be accounted for in your products. II. Darken the bubble to indicate if reactants or products are favored for the equilibrium.
  1. ( 16 points) Provide IUPAC systematic names for the compounds shown below:
  2. (8 points) Name the following Newman projections according to IUPAC rules.
  1. ( 21 points) Provide the appropriate structure indicated in each box below:
