Questions asks Which reaction in Figure 1 results in one or more new bonds with angles of less than 120°?
In order to answer this question you must determine the hybridization and know which hybrization state correspond to those below 120 degrees.
Question though before I add it to all the other bond angle cards. I personally think this tag should be on all the cards testing angles from this table or are we extremely extremely specific and just should tag the angles under 120 degrees with this Uworld QID.
