How many carbon atoms are in propane

• 1

• 2

• 3

• 4

Answer explanation

Propane is a hydrocarbon with three carbon atoms. It is composed of three carbon atoms and eight hydrogen atoms. The correct answer is 3, as it represents the number of carbon atoms in propane. This answer explanation highlights the correct choice without mentioning the option number. Propane is commonly used as a fuel for heating and cooking due to its high energy content and clean burning properties. It is also used as a propellant in aerosol products.

How many carbon atoms are in ethane?

• 1
• 2
• 3
• 4

Which of the following elements is required in an organic compound?

• nitrogen
• oxygen
• carbon
• sodium

What type of molecule is it:

• alkene
• alkyne
• alkane
• amino acid

The "ane" ending in "alkane" tells someone that they are dealing with _________-bonded carbons.

• single

• double

• triple

• quadruple

Answer explanation

The "ane" ending in "alkane" indicates that the carbons are single-bonded. This means that each carbon atom in the alkane molecule is connected to four other atoms or groups of atoms by single bonds. The other options, such as double, triple, or quadruple, would indicate multiple bonds between the carbon atoms, which is not the case for alkane molecules. Therefore, the correct choice is single-bonded carbons.
