the higher the polarity on a functional group, the more reactive it is. If a functional group is non-polar, it doesn't react with anything without a LOT of energy.
For example: a hydrophobic functional group would avoid water at all cost, because it is non-polar, whereas water is polar. Try not to think of this as a "likes repel" sort of thing, but rather that a non-polar functional group is one that has no charge on it, and a polar group has a (+) or (-) charge. While it is true that two (+)'s will repel each other, if there is a (+) functional group, there is likely a (-) one on the other side, which would cause the molecule to flip around and bond that way.
Essentially, polarity of a functional group functions as the + or - charge used to bond to the opposite charge of another molecule/functional group.

Which chemical bond stores the most energy?
convalent bonds have the greatet bond energy.
What kind of bond gives water its important properties?
Two angled polar bonds
Can an electon be completely taken away from another atom in a convalent bond?
No, the atoms in a covalent bond are shared between atoms and even when the sharing is not equal, polar covalent bonds, it is still sharing and not electron is pulled into another elements valance shell.
Are convalent bonds formed from sharing of valence electrons?
Covalent bonding.
Is the bond between nitrogen and hydrogen polar or non-polar?
Oxygen is an element, not a bond. It will form polar bonds with most other elements, though because it is very electronegative. However, when it bonds with itself as in O2 the bonds are nonpolar.
How convalent bond develops ionic character?
Covalent bonds have ionic "character" when they are polar. The more polar, (greater the electronegativity difference) the more ionic character.
What are electrons in convalent bonds?
Atoms share electrons in covalent bonds.
Does sodium chloride have convalent bonds between their atoms?
Sodium chloride has ionic bonds.
What molecules form proteins when linked with convalent bonds?
Animo acids
What best describes convalent bonds?
Sharing of electrons. Generally this involves pirs of electrons forming bonds.
How many pi bonds are there in a triple convalent bond?
Two pi bonds and one sigma bond.
Which chemical bond stores the most energy?
convalent bonds have the greatet bond energy.
What is the definition of polar convalent bond?
A polar covalent bond is a type of chemical bond where electrons are unequally shared between two atoms. This creates a partial positive charge on one atom and a partial negative charge on the other. Polar covalent bonds occur between atoms with different electronegativities.
What molecules form proteins when linked together with convalent bonds?
Animo acids
Is water composed of polar bonds?
Yes, water has polar bonds, and is a very polar molecule.
What shows the kind and proportion of atoms of each element that forms a particular compound?
Convalent bonds
What kind of bond gives water its important properties?
Two angled polar bonds
