TIP4P/2005 is used to describe water. This structure consists of two hydrogen atoms bonded to one oxygen atom (Figure2.3). The nature of the atomic structure of water causes its molecules to have unique electrochemical properties. The hydrogen side of the water molecule has a slight positive charge (Figure2.3). On the other side of the molecule a negative charge exists. This molecular polarity causes water to be a powerful solvent and is responsible for its strong surface tension. Molecule of water consists of two O–H bonds of length 0.096 nm at an angle of 109.47ᵒ Other basic properties of water are its size, shape and polarity.
methanol is a polar material and has a relatively high conductivity compared to non-polar hydrocarbon. Compare the structure of water and methanol, which can be seen that the atoms of the two substances are hybridzed sp3applications is the same. The C-O-H bonds an angle of 108.9° for methanol. The H-O-H bonds angle between the spread of 104.5°. The reason for this is because the methyl group. Larger than a hydrogen atom, a hydrogen atom is pushed. Result is electron pairs at non-bonding of methyl groups and hydrogen atoms are pushed less than in the case of water. The O-H bonds length of both water and methanol are equal is 0.96A° but C-O bonding in methanol have bond length more than is 1.4A°. This reflects the influence of the length of the covalent radius of carbon length more than hydrogen.
