Question

among the following London forces are maximum in 1.Hcl 2.HBr 3.HI 4.all are equal​

Answer 1

Answer:

all are equal

Explanation:

London forces do not depend on the halogen

Answer 2

ANSWER:-

• HCl has the maximum London forces.

EXPLANATION:-

• London forces are the weakest intermolecular attractive forces also known as dispersion forces.

• London forces can be indicated on the basis of the interaction present between the molecules (the more the interactive molecular force less will be the London forces).

• If a similar type of interactive force is present, then we have to follow the magnitude of the interaction.

• For the given hydrides of group 17 elements, HF has hydrogen bonding between its molecule and the rest of the compounds have vander Waals interaction.

• Given compounds HCl, HBr and HI have Vander Waals interaction, so now we have to assess the magnitude of interaction.

• Interaction of Vander Waals is directly proportional to mass and increases with an increase in mass. Out of HCl, HBr and HI, the mass of HCl is minimum so it has less magnitude of vander Waals forces and hence its London Forces will be the maximum.

Hence, HCl has the maximum London forces.
