Post Midterm 1. . . - CHEMISTRY COMMUNITY I came out of midterm 1 extremely confident and felt like I had done everything I could to prepare myself for the exam My solutions were well worked out and I had done every textbook question (and understood them for prep) and I still scored below average Does anyone have any tips? I feel so stuck especially after going through this in 14A where I study so hard but no matter what I score
Bent vs Angular - CHEMISTRY COMMUNITY Bent and angular are interchangeable A shape is bent or angular due to stronger repulsion with a lone pair A shape that has a steric number of 3 with two bonding pairs and 1 lone pair has stronger repulsion from the lone pair, making the bond angle less than 120 degrees A shape with a steric number of 4 that has 2 bonding pairs and two lone pairs has stronger repulsion from the lone pair
