Question

Which of the following has weakest London dispersion forces
a. F2
b. Cl2
C. Br2
d. I2​

Answer 1

Explanation:

London Dispersion Forces. The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

Answer 2

Answer:

a.F2 molecule

Explanation:

London dispersion forces are the type of intermolecular forces in which it intanstaneously make the non polar molecule to polar molecule

factors on which LDF depends are as under

i.e , 1.it depends upon the size of molecule

it means the larger the size the larger will be the LDF , size of molecule and LDF are directly related

2.shape of molecule

shape of molecule is also directly related with LDF , the more complex the shape the more LDF are there.

hence, the F2 molecule have smaller size than other halogens that's why it has weakest LDF
