Why is methane insoluble but methanol is soluble?
Generally speaking 'like dissolves like' so when you thinking if a molecule can dissolve in a particular solvent, you need to decide what type of bonding that solvent can exhibit and what bonding the molecule in question exhibits. So for example water can exhibit hydrogen bonding. This means for something to be able soluble in water, it too needs to be able to exhibit hydrogen bonding. Methane only contains hydrogen and carbon and thus, will not exhibit hydrogen bonding. However, methanol has carbon, hydrogen and oxygen and therefore, can exhibit hydrogen bonding. As a result, using the 'like dissolve like' approach we can see why methane will be insoluble in water but methanol will be soluble.
What is a group of water molecules held together by?
Bonds. Covalent bonds are the result of sharing of electrons. Ionci bonding is by electrostatic attraction.
Why are oh absorptions broad and co absorptions sharp?
Because hydrogen bonds between the OH components alter the vibration frequency slightly. The broad band is the result of many such interactions between molecules in the sample. For CO components there is no hydrogen bonding hence the absorption is sharp.
What makes water adhesive?
cohesion-- Water molecules stick to each other. adhesion-- Water molecules stick to other molecules. Water is a polar molecule because of oxygen is more electronegative. Hydrogen bonds create surface tension and result it water's cohesive and adhesive properties. Hydrophobic = repel water Hydropholic = affinity for water. ...... hahaha XD
What is the cohesive forces between water molecules result in a tight elastic skin at the boundary between the liquid and the air?
surface tension
What is a direct result of hydrogen bonding?
cohesion and adhesion
The tendency of water molecules to stay close to each other as a result of hydrogen bonding?
This is called hydrogen bonding.
What are two properties of water that result from water tendency to form hydrogen bonds?
Water is formed with 2 hydrogens and one oxygen. The oxygen has a strong pull for electrons, making the oxygen negatively charged but making the hydrogen atoms slightly positive. This is called polarity. Since the hydrogen is slightly positive and the oxygen is negative, this makes the hydrogens in the molecules interact with oxygens in other water molecules, thus, creating hydrogen bonds. Cohesion & adhesion result. Water is very cohesive. It is also a good adhesive. High melting point and high boiling point also result from hydrogen bonding.

Why water is unusual?
It has much higher boiling and melting points than would be expected from its molecular size. This is a result of strong hydrogen bonding. Its solid form is less dense than the liquid, because the hydrogen bonding creates a very open structure.
What is hydrogen embrittlement?
Hydrogen embrittlement is a phenomenon that occurs when some metals and alloys are exposed to hydrogen and absorb a sufficient amount of it. The presence of hydrogen interrupts the normal delocalization of bonding electrons in metal objects, and as a result, the metal object loses most or all of its ductility, breaking easily when deformed.Hydrogen embrittlement is the process by which various metals, most importantly high-strength steel, become brittle and fracture following exposure to hydrogen.
Why is water considered unusual?
It has much higher boiling and melting points than would be expected from its molecular size. This is a result of strong hydrogen bonding. Its solid form is less dense than the liquid, because the hydrogen bonding creates a very open structure.
Is caffeine the result of ionic bonding or covalent bonding?
Caffeine is a covalent compound.
What is a group of water molecules held together by?
Bonds. Covalent bonds are the result of sharing of electrons. Ionci bonding is by electrostatic attraction.
What kind of bond is formed between water molecules?
Hydrogen bonding is usually formed between one lone pair of electrons of the oxygen atom of one water molecule and the hydrogen atom of another water molecule. Hydrogen bonding forms as a result of electro-negativity difference between oxygen atom and hydrogen, with oxygen being more electro-negative.
What is the result of NaCl bonding?
ionic bond
What does the secondary structure of a protein result from?
The secondary structure of a protein results from hydrogen bonds.
