Which of the following is incorrect with respect to physical properties of alkyl halides?

Alkyl halides are colourless but alkyl bromide and iodides develop colour when exposed to light.

Though alkyl halides are polar, still they very slightly soluble in water.

The nature of intermolecular forces in alkyl halides are dipole-dipole and van der Waals' forces.

The boiling point of isomeric haloalkanes increase with increase in branching.

Text Solution

Verified by Experts

The correct answer is:

As the branching increases for isomeric haloalkanes, there will be decrease in van der Waals' forces and thus boiling point also decreases.
