Terms in this set (10)
Which molecule will have a double bond?
In H2CO, carbon and oxygen form a double bond in order to satisfy the octet rule.
Which of the following is an exception to the octet rule?
Sulfur in SO2−4 is an exception to the octet rule.
How many electrons does hydrogen need to fill its outermost shell?
The octet rule predicts that carbon will tend to make ____ bonds.
4- With four valence electrons, carbon will gain an octet by making four covalent bonds.
We can predict the number of bonds an atom can form from:
the number of electrons needed to form an octet
The octet rule determines that fluorine will tend to make ____ bond(s).
1-With three lone pairs and one unpaired electron, fluorine will gain an octet by making one covalent bond.
If an atom has a full octet, it will have:
The atom may or may not have some formal charge and/or covalent bonds, but it certainly will have the electron configuration of the nearest noble gas.
If a nitrogen atom has four covalent bonds, what will be its formal charge?
+1 bc If a nitrogen has four bonds, it will contribute four electrons to the Lewis structure, which is one less than its typical valence of five. That means a formal positive charge.
Typically if nitrogen has a formal positive charge, it is participating in ____ covalent bond(s).
4-If nitrogen has four bonds and zero lone pairs, that would cause a formal positive charge.
If a formal negative charge must be present on a molecule, which element would be preferred to accommodate it?
The negative charge will prefer to be on the most electronegative atom possible, and of the above options, that would be oxygen.
