  • Q:

    Phosphorus had 3 allotropes: red, white, and black. White is most reactive due in large part to having 60 degree bonds in a tetrahedral formation. Which of the following best explains the reason for the bond angle increasing reactivity?

     

    A

    60 degree angles are energetically favorable, making the allotrope less stable and thus more reactive.

    B

    60 degree angles are energetically unfavorable, making the allotrope less stable and thus more reactive.

    C

    60 degree angles are energetically favorable, making the allotrope more stable and thus more reactive.

    D

    60 degree angles are energetically unfavorable, making the allotrope more stable and thus more reactive.
