Students were enquired to answer a question at education and to claim what is most important for them to succeed. One which response stood out from the rest was practice. Persons who usually are successful do not become successful by being born. They work hard and persistence their lives to succeeding. This is how you can fulfill your goals. following are one of the answer and question example that you could possibly benefit from to practice and improve your information and also give you insights that might help you to preserve your study in school.
Question:
Why is BrCl5 nonpolar when it’s Asymmetrical? Aren’t symmetrical molecules suppposed to be polar?
Answer:
BrCl₅ is non-polar as
- BrCl₅ is an asymmetrical molecule, the bromine is present in the center and five chlorine are present around the bromine atoms. This will form a square pyramidal structure and the intermolecular forces present are the dispersion forces.
- Due to low difference of electronegativities, BrCl₅ is a nonpolar molecule.
- Br-Cl bonds are nonpolar because the difference between their electronegativities is: Br: 2.96 , Cl: 3.16
- Δx= 3.16 – 2.96 = 0.2
- BrCl₅ has nonpolar bonds.

From the answer and question examples above, hopefully, they may help the student resolve the question they had been looking for and take note of everything that declared in the answer above. Then will be able to have some sharing in a group discussion and also learning with the classmate somewhere around the topic, so another student also absorb some enlightenment and still keeps up the school learning.
