20 Questions
Why does an ideal contact distance matter for van der Waals interactions?
Too far a distance will result in no van der Waals interactions
What type of interaction is the hydrogen bond acceptor involved in?
Hydrogen bonding
What causes water to have a high surface tension and be a good solvent for different chemicals?
Oxygen's higher electronegativity than hydrogen
What effect do hydrophobic molecules have on the structure of water's hydrogen bonding?
Disrupt its stability
What is the octet rule?
The tendency of atoms to gain, lose, or share electrons to achieve a stable electron configuration with 8 valence electrons
Which type of bond occurs between nonmetals and involves the sharing of electron pairs?
Covalent bond
How are the bases in the DNA double helix held together?
Van der Waals interactions
What characterizes a polar covalent bond?
Development of partial positive and negative charges on different parts of the molecule
What type of atom is an electronegative atom that is covalently bonded to a hydrogen and serves as a hydrogen bond donor?
An electronegative atom such as N, O, C or F
Which type of bond occurs between an electronegative atom and a hydrogen that is covalently bonded to another electronegative atom?
Hydrogen bond
What type of bond occurs between nonmetals and involves the sharing of electron pairs?
Covalent bond
Which type of bond is the strongest and occurs when 2 or more atoms share an electron pair?
Triple bond
What causes partial (-) and (+) charges to develop on different parts of a molecule in a polar covalent bond?
Unequal sharing of electrons
Which type of bond occurs between metals and nonmetals through the transfer of electrons?
Ionic bond
What type of atom serves as a hydrogen bond donor in hydrogen bonds?
Hydrogen (H)
What characteristic defines non polar covalent bonds?
Equally shared electrons
Which type of covalent bond is the weakest with the greatest distance between bonds?
Single bond
What is the net charge in non polar covalent bonds due to equally shared electrons?
+0
What is the strongest non covalent bond that occurs between metals and nonmetals?
Which type of atom tends to spend more time close to one atom than the other in a polar covalent bond?
Test your knowledge of the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a stable electron configuration, and electronegativity, which is an atom's tendency to attract shared electrons to itself. Learn about the stability of noble gases and the behavior of electronegative and electropositive elements.
