Physical Properties Flashcards
1
Q
Nature of Ethanal
A
Volatile liquid
2
Q
Nature of Methane
A
Gas at room temperature
3
Q
Boiling point compared to hydrocarbons and ethers
A
They are higher due to weak molecular associations arising out of dipole-dipole interaction
4
Q
Boiling point compared to alcohols
A
lower than alcohols due to absence of intermolecular hydrogen bonding
5
Q
Miscibility with water
A
Methanal, ethanal and propanone as they form hydrogen bond with water
6
Q
Solubility
A
Decreases as length of alkyl chain increases
7
Q
All aldehydes and Ketones are soluble in what type of solvent.
A
Organic solvents like benzene, ether, chloroform and methanol.
8
Q
Odour
A
Lower aldehydes have pungent odours, As size increases, the odour becomes less pungent.
