(ii) Arrange RCl and RBr, Rl RCE in decreasing order of boiling point.

Explanation

To compare alkyl halides (R-X) and alkanes (R-H) in terms of dipole moment, solubility in water, and boiling points of RCl, RBr, and RI, we can analyze each aspect step by step.

### Step 1: Dipole Moment
1. **Understanding Dipole Moment**: The dipole moment is a measure of the separation of positive and negative charges in a molecule. It arises when there is a difference in electronegativity between the atoms involved in a bond.
2. **Comparison**: In alkyl halides (R-X), the halogen (X) is more electronegative than carbon (R). This creates a polar bond where the electron density is pulled towards the halogen, resulting in a positive charge on the carbon and a negative charge on the halogen. Therefore, R-X has a significant dipole moment.
3. **Alkanes (R-H)**: In alkanes, the carbon-hydrogen bonds are relatively non-polar because carbon and hydrogen have similar electronegativities. As a result, alkanes do not have a significant dipole moment.
4. **Conclusion**: The dipole moment of R-X is greater than that of R-H.
