Arrange the following in order of increasing enthalpy of atom combination and decreasing bond length.

Question

Quizplus · Accepted Answer

The enthalpy of atom combination is related to bond strength, which generally increases with shorter bond lengths. Iodine has the longest bond length and weakest bond, while fluorine has the shortest bond length and strongest bond. Thus, the order is I₂ > Br₂ > Cl₂ > F₂ for increasing enthalpy of atom combination and decreasing bond length.
