chapter 14 Flashcards
1
Q
uses of methanol
A
high performance fuel- efficient combustion
chemical feedstock
2
Q
why are alcohols less volatile, have higher mp and greater water solubility than alkanes
A
- alkanes have non polar bonds
- alkanes have weak London forces
- alcohols have a polar O-H bond, because of difference in electronegativity
- alcohol molecules are therefore polar
- weak London forces but also have strong h bonds
3
Q
oxidation, distillation of a primary alcohol
A
produces an aldehyde and water
acidified potassium dichromate
4
Q
oxidation, reflux of a primary alcohol
A
produces a carboxylic acid and water
5
Q
oxidation of secondary alcohol
A
produces a ketone and water
reflux
6
Q
dehydration of alcohol
A
water molecule is removed
acid catalyst- eg H3PO4
produces an alkene
