How To Study for Chemistry

Chemistry is one of those classes you either love or dread. At the high school level chemistry is usually not a required course – it's an elective. However, most reputable colleges require all undergraduate students to take at least one chemistry course as a prerequisite to graduation. If you plan on pursuing a career in medicine, engineering, or a field of natural science, then you're likely going to be required to take at least one chemistry course before you graduate. Chemistry is a challenging subject for most people, but it doesn't have to be. The number one reason people struggle with chemistry is that they don't approach it the right way. Below we'll explore proven strategies and techniques that will, if applied, improve your ability to study and learn chemistry.

Cloud [144]

Answer:

4. trigonal planar symmetry.

Explanation:

The sp2 hybridization is formed with one s and two p atomic orbitals and form  trigonal planar symmetry. In sp2 hybridization, there are same valence shell in both the orbitals and it gives three equivalent sp2 hybridized orbitals that are separated by 120 degrees giving trigonal planar symmetry.

Hence, the correct answer is "4. trigonal planar symmetry.".
