Alkanes are called as _?

Correct answer: B. Paraffins

  • A. Olefines
  • B. Paraffins
  • C. Reactive
  • D. All of these options are correct

Explanation

Alkanes are also called paraffins, while alkenes are also called olefins. Paraffin comes from the Latin term 'param affinum' meaning 'less affinity' in other words 'less reactivity'. Alkanes have only single bonds which are sigma covalent, thus alkanes are called paraffin because they have a lesser affinity toward general reagents.
