Question 1
Question
What is the structure of a Primary alcohol?
Answer
Question 2
Question
The boiling points of alcohols increases as the chain length [blank_start]increases[blank_end] because there are [blank_start]more[blank_end] surface area contacts and stronger [blank_start]induced dipole-dipole[blank_end] interactions (London forces). Hydrogen bonds also increase the intermolecular force of attraction. The higher the forces of attraction the [blank_start]more[blank_end] energy needed to break the bonds.
Answer
-
increases
-
decreases
-
more
-
fewer
-
induced dipole-dipole
-
permanent dipole-dipole
-
permanent dipole-induced dipole
-
more
-
less
Question 3
Question
Which of these statements about alcohols are correct?
Answer
-
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.
Question 4
Question
Fill in the state symbols for this [blank_start]combustion[blank_end] reaction.
C ₂H₅OH ([blank_start]l[blank_end]) + 3O₂ ([blank_start]g[blank_end]) ---> 2CO₂ ([blank_start]g[blank_end]) + 3H₂O ([blank_start]l[blank_end])

Question 8
Question
Esterification is reversible and has a slow rate of reaction.
Answer
- True
- False
Question 9
Question
For esterification to work a nickel catalyst is added to a test tube in a 100`C water bath.
Answer
- True
- False
Question 10
Question
All large molecule Esters are soluble in water.
Answer
- True
- False
Question 11
Question
Dehydration is a type of [blank_start]elimination[blank_end] reaction where water is [blank_start]lost[blank_end] from an organic compound.
The alcohols are heated under reflux with a strong [blank_start]acid[blank_end] catalyst (H₂SO₄) at [blank_start]170[blank_end]'C.
π-bonds form between adjacent [blank_start]carbon[blank_end] atoms and a [blank_start]water[blank_end] molecule is released from the H in the acid and the OH in the alcohols functional group.
Answer
-
elimination
-
lost
-
170
-
acid
-
water
-
carbon
Question 12
Question
