Concept explainers
(a)
Interpretation: The reason as to why one isomer has a lower melting point but higher boiling point is to be stated.
Concept introduction: Symmetry is one of the important factors for deciding the melting point of a compound. Symmetrical molecule will have high melting point than unsymmetrical molecule. The boiling point of compound is higher, if it contains more polarizable atoms. The boiling point also increases with increase in surface area. Branched chain
(b)
Interpretation: The reason behind the small difference in the boiling points of the given compounds, but a huge difference in their melting points is to be stated.
Concept introduction: Symmetry is one of the important factors for deciding the melting point of a compound. Symmetrical molecule will have high melting point than unsymmetrical molecule. The boiling point of compound is higher, if it contains more polarizable atoms. The boiling point also increases with increase in surface area. Branched chain alkanes have low boiling point than straight chain alkanes because in branched chain alkanes, surface area is less.
