Bonds
Energy
Energy needes to break the bond
Kcal/mol
KJ/mol
Covalent bond
Don´t break for warming
Break with specific reactions
simple bond
Allows simple rotation of the molecule
Doble bond
Shorter and stronger
More rigid and less flexible atoms
Polar structure
Negative pole at one extreme
Positive pole at one extreme
In water solutions
10 to 100 times stronger
Non covalent
Weaker
