Solution
Correct Answer:
CₒH₂ₒ₊₂
Alkanes are saturated hydrocarbons containing only single covalent bonds (C−C and C−H).
- General Formula: CnH2n+2, where 'n' is the number of carbon atoms.
- For n=1: CH4 (Methane)
- For n=2: C2H6 (Ethane)
- Alkanes are also known as paraffins (Latin: parum affinis = little affinity) because they are relatively unreactive due to the strength of C−C and C−H sigma bonds.
This easy difficulty chemistry question is from the chapter hydrocarbons, covering the topic of alkanes. It appeared in the 2025 exam.
