Carbonyl Compounds Flashcards
(6 cards)
Use of methanal
Was used by biologists to preserve specimens but now restricted due to toxicity. Still raw material for the manufacture for a range of thermosetting plastics.
Use of propanone
Common solvent and used as nail polish remover
Intermolecular forces in carbonyl compounds
London forces and dipole-dipole interactions
Why is hydrogen bonding possible with water
Between carbonyl group and OH of water due to long pair of oxygen atom
Why are bps of carbonyl compounds lower than alcohols of same size
As cannot form hydrogen bonds between molecules
Why do longer chain carbonyl compounds not dissolve in water
As carbon chain lengthens London forces stronger and energy to overcome London forces becomes stronger than energy released in hydrogen bonding with water meaning cannot disrupt hydrogen bonding network/ overcome London forces between chains
