Which of the following statements is true about alkanes?
Alkanes are aromatic compounds with the formula CnH2n-6.
Alkanes contain at least one double bond in their structure.
Alkanes are saturated hydrocarbons with the formula CnH2n+2.

What is the significance of nomenclature in organic chemistry?
Nomenclature is only important for inorganic chemistry.
Nomenclature has no impact on the understanding of chemical reactions.
Nomenclature is a method for predicting the properties of compounds.
Nomenclature is significant as it standardizes the naming of organic compounds, enabling clear communication and identification.
Which of the following is a characteristic of conjugated dienes?
They exhibit resonance stabilization due to alternating double bonds.
They do not participate in electrophilic addition reactions.
They are less stable than isolated double bonds.
They contain only single bonds between carbon atoms.
What is the primary difference between cyclic and acyclic alkanes?
Cyclic alkanes contain rings of carbon atoms, whereas acyclic alkanes do not.
Cyclic alkanes are always saturated, while acyclic alkanes can be unsaturated.
Acyclic alkanes contain rings of carbon atoms, while cyclic alkanes are linear.
Cyclic alkanes have a higher boiling point than acyclic alkanes.
