Multiple Choice
Which of the following statements about alkanes is false?
A
Alkanes undergo combustion reactions.
B
Alkanes have the general formula CnH2n+2.
C
Alkanes are saturated hydrocarbons.
D
Alkanes can form hydrogen bonds with water.
Verified step by step guidance
1
Understand the nature of alkanes: Alkanes are hydrocarbons that consist only of single bonds between carbon atoms, making them saturated hydrocarbons.
Review the general formula for alkanes: The general formula for alkanes is CnH2n+2, where 'n' is the number of carbon atoms.
Consider the types of reactions alkanes undergo: Alkanes are known to undergo combustion reactions, where they react with oxygen to produce carbon dioxide and water.
Examine the concept of hydrogen bonding: Hydrogen bonds typically occur between a hydrogen atom and a more electronegative atom like oxygen or nitrogen. Alkanes, being nonpolar, do not have the ability to form hydrogen bonds.
Identify the false statement: Since alkanes are nonpolar and cannot form hydrogen bonds with water, the statement 'Alkanes can form hydrogen bonds with water' is false.
