What is the structure of a Primary alcohol?
The boiling points of alcohols increases as the chain length increases decreases( increases, decreases ) because there are more fewer( more, fewer ) surface area contacts and stronger induced dipole-dipole permanent dipole-dipole permanent dipole-induced dipole( induced dipole-dipole, permanent dipole-dipole, permanent dipole-induced dipole ) interactions (London forces). Hydrogen bonds also increase the intermolecular force of attraction. The higher the forces of attraction the more less( more, less ) energy needed to break the bonds.
Which of these statements about alcohols are correct?
Volatility is where a substance can easily evaporate at RTP.
Hydrogen bonds decrease the volatility of an alcohol.
Hydrogen bonds increase the volatility of an alcohol.
The solubility of an alcohol decreases when the chain length increases.
Alcohols are non-polar molecules.
Volatility increases as the boiling point increases.
Fill in the state symbols for this combustion oxidation reduction( combustion, oxidation, reduction ) reaction.

HCl
C₂H₆
What is the functional group of an ester?

Label the reactants and products of this reaction.
Esterification is reversible and has a slow rate of reaction.
For esterification to work a nickel catalyst is added to a test tube in a 100`C water bath.
All large molecule Esters are soluble in water.
Dehydration is a type of reaction where water is from an organic compound.
The alcohols are heated under reflux with a strong catalyst (H₂SO₄) at 'C.
π-bonds form between adjacent atoms and a molecule is released from the H in the acid and the OH in the alcohols functional group.
The general formula for halide substitution is ROH + HX --> RX + H₂O
