Students were asked over to answer a question at education and to tell what is most important for them to succeed. Of the numerous replies, the one that that stood out was practice. Persons who are definitely successful do not become successful by being born. They work hard and dedicate their lives to succeeding. If you would like to get your goals, keep this in mind! right below some question and answer examples that you can potentially use to upgrade your knowledge and gain insight that will help you to preserve your school studies.
Question:
Which formula represents a nonpolar molecule containing polar covalent bonds?
Answer:
The formula that represents a nonpolar molecule containing polar covalent bonds is O=C=O.
A bond is polar when there is a high difference in electronegativity between the atoms in the bond. Carbon and oxygen form polar bonds because of the significant electronegativity difference between the two atoms.
However, the polarity of individual bonds does not mean that the molecule will be polar because dipole moment is a vector quantity. The direction of the dipole moment is also important.
In O=C=O, the dipoles are oriented in opposite directions therefore, they cancel out and the molecule is nonpolar even though it contains polar bonds.
They can hopefully assist the student take care of the question by make use of the questions and answer examples. You could potentially then have a discussion with your classmate and continue the school learning by studying the problem collectively.
