Which of the following is the weakest type of intermolecular force?
o Hydrogen bonding
o Induced dipole
London dispersion
o Dipole-dipole

London Dispersion

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
