Answer: Option (3) is the correct answer.

Explanation:

It is known that more is the carbon atoms attached linearly into a molecule more will be the boiling point of the molecule.

Also, more is the branching in a molecule, less will be the boiling point of atom.

Therefore, out of the given options pentene has highest number of carbon atoms, hence, pentene has the highest normal boiling point.

Pentene has the highest boiling point.

The number of carbon atoms attached linearly in a molecule will determine its boiling point, that is, the more carbon atoms attached, the more its boiling point. the chemical formula for the hydrocarbons is as follows: Pentene is C5H10, butene is C4H8, ethene is C2H4 and propene is C3H6,

Further Explanation

Pentene is a compound that has five carbon atoms and a double bond. The chemical formula for pentene can be expressed as C5H10. If we split the name of the compound, then we have ‘pent’ which means 5 and ‘ene’ which means a double bond within the molecule.

However, pentene can exist as three isomers, which are 1-pentene, cis-2-pentene, and trans-2-pentene. Isomers are molecules with the same formulas but different structures. Isomers do not share the same similar properties.

Butene is a series of alkanes and its general chemical formula is C4H8. Butane contains 4 carbon atoms and 8 hydrogen atoms.

Butene can form different molecular structures or isomers and these include

  • alpha-butylene
  • cis-beta-butylene
  • trans-beta-butylene
  • isobutylene

ethene: the general chemical formula for ethene is C2H4, it is the major organic chemical. It is used to produced polymers and other chemicals such as ethanol.

Propene is also called methyl ethylene and its general chemical formula is C3H6. It is made up of one double bond.
