| Question | Answer |
| What is the general formula of alcohols | CnH2n+1 OH |
| What is the functional group of Alcohol | (OH) Hydroxyl |
| Draw primary, secondary and tertiary alcohol (using methanol) | check in chem book 19/04/18 |
| What are the physical properties of alcohols ? Refer to boiling point and compare it to Alkanes (3) | - has stronger boiling point then alkanes - alkanes im = vanderwaals forces alcohol im = hydrogen bonding strongest force |
| Is ethanol soluble in water and why? (2) | soluble in water contains polar OH (Hydroxyl group) |
| Which one is less soluble in water hexan-1-ol or ethanol (4) | hexan-1-ol longer hydrocarbon chain lower solubility dominates physical properties of molecule |
| (Write and equation to show oxidation using acidified potassium dichromate) | - cr207(2-) +14H+ 6e- > 2Cr(3+) + 7H20 |
| What colour change in this reaction what is being reduced (2) | orange to green cr |
| Draw symbols for -Aldehyde -Carboxylic acid - keytone | look in chem book 20/04/18 |
| If the alcohol is primary and distilled, what are the conditions |
