Polarity is a physical property of compounds which relates other physical properties such as solubility, boiling and melting points and intermolecular interactions between molecules.
True
False
The polarity of substances determines their solubility in different solvents.
True
False
The molecular geometry of water is trigonal pyramidal.
True
False
A molecule shape is a three-dimensional arrangement of atoms or bonding
groups around a central atom. The molecular shape is governed
by the valence shell electron repulsion (VSEPR) theory.
The first and second statements are true
The first and second statements are false.
The first statement is true while the second statement is false
The first statement is false while the second statement is true.
Sulfur hexafluoride (SF6) has six bonded electrons and no lone pair
in its central atom.
True
False
H, N, O or F?
What type of bond is involved if the electronegativity difference is <O.5?
Covalent Bond
Ionic Bond
Polar Covalent Bond
Non-polar Covalent Bond
When you have Si-O, what is the polarity?
nonpolar
polar
ionic
Which is TRUE about polar bonds?
They are present in metals
They are responsible for the formation of ionic compounds.
They always result in the formation of polar molecular compounds
They may result in nonpolar covalent compounds depending on
molecular geometry.
The general trend of electronegativity as you move from top to bottom
of the periodic table is increasing.
True
False
Is this molecule polar or non-polar?
Polar
Non-polar
What type of chemical bond holds the atoms of water molecule together?
Ionic bond
Hydrogen bond
Polar covalent bond
Nonpolar covalent bond
