Question

Which of the following are called paraffins?

• A. Alkanes
• B. Alkenes
• C. Alkynes
• D. Alkyls

Answer 1

The Correct Option is A

Paraffins are a group of hydrocarbons that fall under the category of alkanes. Alkanes are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms and are saturated with hydrogen atoms. The general formula for alkanes is C_nH_2n+2, where 'n' represents the number of carbon atoms in the molecule. Examples include methane (CH₄), ethane (C₂H₆), and propane (C₃H₈). Alkanes are called paraffins due to their low reactivity and waxy texture in heavier members of the series.

Answer 2

Correct answer: Alkanes

Explanation: 
- Alkanes are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms.
- They are chemically less reactive compared to alkenes and alkynes.
- Due to their low reactivity, they are called paraffins, which means "little affinity" (from Latin).

So, alkanes are referred to as paraffins.
