Aryl halides are extremely … Assertion and reason both are correct statements but reason is not correct explanation for assertion. Know exam pattern, new marking scheme, sample paper & more. These attractions get stronger as the molecules get longer and have more electrons. The carbon-halogen bonds (apart from the carbon-iodine bond) are polar, because the electron pair is pulled closer to the halogen atom than the carbon. Remember: The patterns in boiling point reflect the patterns in intermolecular attractions. CBSE has reduced the syllabus for class 10 & 12 exam 2021, date sheet can release soon.

Among isomeric alkyl halides, the boiling point decreases with the increase in branching in the alkyl group, because with branching the molecule attains spherical shape with less surface area. Energy is released when new attractions are set up between the halogenoalkane and the water molecules.
