Explain why Alkenes have higher melting points than the alkanes with the same carbon skeleton.

Why amines have higher boiling points than corresponding alkanes ?

Why n- Pentane has higher boiling point than isopentane ?

Explain why propanol has a higher boiling point than hydrocarbon butane ?

Explain why ionic solids have high melting and boiling points.

Which of the statement is correct ? I. Melting point of alkane increases with increase of C atoms and with increase in branching. II. Boiling point of alkane increases with increase of C atoms but with decrease in branching. III. Cycloalkanes have lower boiling point than normal alkane with same numer of C atoms. IV. Alkenes have lower boiling point than same number of C atoms in alkanes.

Explain why the covalent solids have high melting and boiling points.

Why do alkaline earth metals have higher melting points than group 1 elements ?

Carboxylic acids have higher boiling points than alcohols Why?

Acids have much higher boiling points than isomeric esters because :-

Alkanes containing even number of carbon atoms possess higher melting points than those containing odd number of carbon atoms.
