(a)
Interpretation:
The longer bond has to be predicted between O-H hydrogen bond and O-H covalent bond.
Concept introduction:
Hydrogen bonding: It is an
This type of bonding does not sharing of electrons in a covalent bond; it is attraction between the positive and negative poles of charges atoms.
Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms.
(b)
Interpretation:
The stronger bond has to be predicted between O-H hydrogen bond or O-H covalent bond.
Concept introduction:
Hydrogen bonding: It is a electromagnetic attraction between polar molecules with hydrogen bonds to a larger atom (for example oxygen or nitrogen) atoms.
This type of bonding does not sharing of electrons in a covalent bond; it is attraction between the positive and negative poles of charges atoms.
Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms.

The chemist holds a small flame up to the hydrogen balloon. When the balloon pops, the hydrogen explodes in a ball of fire. Based on what you know about breaking and forming bonds, explain which part of the reaction is higher in energy (i.e., does it take more energy to break the bonds of the reactants, or is more energy given off when the product bonds are formed?).
