Question 1

Which of the following best describes the difference between ionic and covalent bonds?

Accepted Answer

Ionic bonds involve the transfer of electrons and are held together by electrostatic interactions, while covalent bonds involve the sharing of electrons between atoms.

Question 2

Given the molecule CH$$_2O$$, how many total valence electrons are present?

Accepted Answer

$$12$$

Question 3

Which element is least likely to form more than one bond in organic molecules?

Accepted Answer

Hydrogen

Question 4

What is the formal charge on the oxygen atom in the Lewis structure of HCO$$_2^-$$?

Accepted Answer

$$-1$$

Question 5

Which of the following is a correct step in drawing a Lewis structure for a molecule?

Accepted Answer

Fill in lone pairs on terminal atoms until the octet is complete or all electrons are used up.

Question 6

Which molecule is an example of a carbon-containing compound studied in organic chemistry?

Accepted Answer

Caffeine

Question 7

What is the formula for calculating formal charge?

Accepted Answer

$$	ext{FC} = v - b - d$$

Question 8

Which of the following statements about expanded octets is correct?

Accepted Answer

Phosphorus and sulfur can have expanded octets.

Question 9

In the context of organic chemistry, which of the following is NOT a course learning goal?

Accepted Answer

Memorizing every chemical reaction in the textbook.

Question 10

Which of the following best explains why the bond in NaCl is considered ionic?

Accepted Answer

Electrons are transferred from Na to Cl, resulting in electrostatic attraction.

Question 11

Which of the following is the correct number of bonds and lone pairs for nitrogen in most organic molecules?

Accepted Answer

3 bonds, 1 lone pair

Question 12

Which of the following is a real-world application of organic chemistry?

Accepted Answer

Understanding the reaction cascade that allows humans to see.

Question 13

Which of the following is true about the octet rule in organic molecules?

Accepted Answer

Carbon typically forms four bonds to satisfy the octet rule.

Question 14

Which of the following is the correct number of valence electrons for oxygen?

Accepted Answer

$$6$$

Question 15

Which of the following is a recommended resource for success in Organic Chemistry I?

Accepted Answer

Question 17

Which of the following is the correct number of bonds and lone pairs for oxygen in most organic molecules?

Accepted Answer

2 bonds, 2 lone pairs

Question 18

Which of the following is the correct number of valence electrons for carbon?

Accepted Answer

$$4$$

Question 19

Which of the following is a correct statement about the grading policy in Organic Chemistry I?

Accepted Answer

The cumulative final can replace your weighted average if you score higher on it.

Question 20

Which of the following is a correct step in predicting the reactivity of organic molecules?

Accepted Answer

Determine where electrons move, in what order, and what products form.
