Answer:
see below
Explanation:
1. Heat energy is added to the substance, weakening the electrical attraction between molecules.
2. Both the melting point and boiling point are lower.
3. dipole
4. Water and ethanol have different molecular structures.
5. The lone pairs of electrons in the oxygen atom causes the molecule to be bent; the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges.

Sorry but I do not the answer to help you but I will advise you to look in internet for better answer and secondly I think your cheating while doing paper
The reaction of benzene with an alkyl chloride and aluminum trichloride is called a Friedel-Crafts alkylation. The aluminum trichloride is a lewis acid that reacts with the alkyl chloride, and this converts the alkyl group into a very good electrophile. The overall reaction is an electrophilic aromatic substitution. A pi bond of the benzene ring will attack the electrophile as a nucleophile and form a new carbon-carbon bond. The result is a monosubstituted isopropyl group on the benzene ring.
However, we are told that the conditions are set up to encourage dialkylation. The isopropyl group is a group that donates electron density through induction. Therefore, it is an ortho- and para-directing group. This means that once one isopropyl group is substituted on to the benzene ring, the second substitution will be favoured in the ortho- and para-positions. In this instance, the major product is the 1,4-disubstituted product. The reason being is that the isopropyl groups are very bulky, and the steric hindrance of having two isopropyl groups adjacent leads to a small amount of this product being formed.
There will also be trace amounts of the meta-substituted product, but the 1,4- and 1,2-substituted products are more favoured.
From the periodic table, you will find that:
mass of Cl = <span>35.453 grams
mass of Na = </span><span>22.989769
Now, since NaCl is formed from the combination of one mole of sodium from one mole of chlorine, therefore, the molar mass of NaCl can be calculated as followed:
molar mass of NaCl = </span>35.453 + 22.989769 = 58.442769 gram/mole
