1

Which of the following properties makes carbon unique in organic chemistry?

Carbon's ability to form stable covalent bonds with other carbon atoms, creating long chains and rings, is a key feature that makes it unique in organic chemistry.

2

Identify the compound with an alcohol functional group.

CH3-CH2-OH has an -OH group attached to a carbon chain, which is the characteristic functional group of alcohols. Other options do not show this functional group.

3

Which of the following functional groups contains a carbon-oxygen double bond?

The carbonyl group (C=O) is characterized by a carbon-oxygen double bond and is found in aldehydes, ketones, carboxylic acids, and other functional groups.

4

Which of the following is the correct IUPAC name for the compound with the structure CH3​CH2​CH2​OH?

The compound has a three-carbon chain (CH3CH2CH2​) with a hydroxyl group (-OH) attached, making it propanol.

5

What is the correct condensed structural formula for 2-methylbutane?

2-methylbutane is a four-carbon chain (butane) with a methyl group (-CH3) attached to the second carbon.

6

Which of the following describes resonance in organic molecules?

Resonance occurs when electrons in a molecule are delocalized over multiple atoms, and the molecule can be represented by multiple resonance forms, each contributing to the true structure.

7

What type of isomerism is exhibited by 1-bromopropane and 2-bromopropane?

1-bromopropane and 2-bromopropane are structural isomers because they have the same molecular formula but differ in the connectivity of atoms (the position of the bromine atom).

8

Which type of organic reaction involves the replacement of one atom or group by another?

A substitution reaction occurs when one atom or group in a molecule is replaced by another atom or group. This is common in reactions involving halides or nucleophiles.

9

Which of the following is an example of a hydrocarbon with only single bonds?

Alkanes are hydrocarbons with only single bonds between carbon atoms, making them saturated hydrocarbons.

10

What is the IUPAC name of the following compound: CH3CH2CH(CH3)CH2OH?

The longest chain contains four carbons (butanol), and the methyl group is attached to the second carbon. The hydroxyl group (-OH) is on the first carbon.
