Question
State the general formula for the homologous series of alkanes.
Answer
The general formula for the homologous series of alkanes is CnH2n+2.
Explanation
This question assesses the student's ability to recall the general formula for alkanes, which is fundamental knowledge in organic chemistry. It focuses on the structural characteristics of alkanes.
Common mistake
Misunderstanding Hydrocarbon Types
Students often confuse alkanes with other types of hydrocarbons, such as alkenes, thinking that all hydrocarbons are alkanes.
To fix this, students should remember that alkanes are saturated hydrocarbons with the general formula CnH2n+2, while alkenes are unsaturated with the general formula CnH2n.
