Suggest a reason for the larger differenece between boiling points of butanol and butanal, although they have almost the same solubility in water.

Is the boiling point of water on a mountaintop the same as that on the ground ?

At isoelectric point the amino acids have least /maximum solubility in water.

Explain the following : (a) Dimethyl ether has a lower boiling point (249K) than ethyl alcohol (351K) although both have same molecular masses. (b) Ethers have low solubility in water but high solubility in conc. H_(2)SO_(4) .

Give reasons - noble gas have low melting and boiling points?

State reasons for the following: primary amines have higher boiling points than tertiary amines.
