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.

- Please explain how to calculate the pH.arrow_forwardI'm having trouble with converting lewis diagrams into VSEPR diagrams. I currently have this example of C2BrCl3 which I want to turn into a lewis structure, but I'm not sure what steps I need to do in order to do so. I have the table written down, however, there's two central atoms so what would I do? There seems to be 4 electron domains on the carbon atom and no lone pairs so it would seem like this shape would be tetrahedral. Here's what I have now.
