Question 1

How many total H atoms are present in the structure shown below?

Accepted Answer

B

Question 2

The compound below is classified as what type of compound?

Accepted Answer

C

Question 3

Which compound is an ether?

Accepted Answer

Compound B (11eaaeeb_de8b_73a7_9547_b970a95a51a1_TB5866_00) is the only compound with an oxygen atom bonded to two separate carbon atoms, which is the defining characteristic of an ether. The other compounds do not have this features and are therefore not ethers.

Question 4

Which formula represents an organic compound?

Accepted Answer

A and B are both inorganic compounds. C represents an element (phosphorus) rather than a compound. D is the only formula that represents an organic compound, as it contains carbon (C) and hydrogen (H) atoms bonded together.

Question 5

Which compound is an aldehyde?

Accepted Answer

The answer of Which compound is an aldehyde?
...

Question 6

Which element is not a common heteroatom in organic compounds?

Accepted Answer

Sodium (Na) is a metal and not a heteroatom commonly found in organic compounds.

Question 7

Which of the following correctly depicts the three-dimensional shape around each carbon in the structure below?

Accepted Answer

The answer of Which of the following correctly depicts the...

Question 8

How many total H atoms are present in the structure shown below?

Accepted Answer

Counting the number of H atoms present in the molecule, we get: 
- 6 H atoms in the six-membered ring on the left
- 6 H atoms in the six-membered ring on the right
- 2 H atoms in the carboxylic acid group
- 4 H atoms in the two NH2 groups 
So the total number of H atoms is 6+6+2+4=18 H atoms. Option B is the correct choice.

Question 13

How many H atoms are bonded to the labeled carbons in the structure below?

Accepted Answer

C1 has two H atoms bonded to it and C2 has one H atom bonded to it.

Question 14

What is the most common multiple bond between carbon and a heteroatom?

Accepted Answer

The carbon-oxygen double bond (C=O), also known as a carbonyl group, is the most common multiple bond between carbon and a heteroatom. This bond is found in a wide variety of organic molecules, including aldehydes, ketones, carboxylic acids, and esters.

Question 15

Accepted Answer

The answer of Which of the following correctly describes the...

Question 16

The compound below is classified as what type of compound?

Accepted Answer

The compound has an ester functional group, which is characterized by a carbonyl group (C=O) bonded to an oxygen atom that is also bonded to an alkyl or aryl group.

Accepted Answer

The answer of Which represents a condensed structure for a...

Question 18

What is the shape around each carbon atom in the structure shown below?

Accepted Answer

The answer of What is the shape around each carbon...

Question 19

How many covalent bonds does carbon generally form in organic compounds?

Accepted Answer

Carbon generally forms 4 covalent bonds in organic compounds, making it tetravalent. This is due to its electron configuration (2 electrons in the first energy level and 4 electrons in the second energy level) which allows it to share electrons with other atoms to achieve a stable octet configuration.

Question 20

How many H atoms are bonded to the labeled carbons in the structure below?

Accepted Answer

C1 has two Hs bonded to it and C2 has one H bonded to it.
