Question

Which of the following statements is/are best suited for the following figure?

• A. The attraction gets stronger as molecules get bigger in size
• B. The boiling point of alkyl halide is in order of $R I >R Br >R Cl >R F$
• C. Magnitude of van der Waals' forces increases as mass of halogen atom increases
• D. All of the above

Answer 1

Answer: (D)

Due to the increase in size and mass of halogen atom, attraction among the molecules get stronger and the magnitude of van der Waals' forces increases. As a result of this, the boiling point of alkyl halide can be arranged as, $RI >R Br >R Cl >R F$.
