Why bond ener...

Question

Why bond energy of fluorine is less than bromine and chlorine??
Bond energy is inversely proportional to atomic size i this true or not??

Open in App

Solution

its due to small size of F atoms , F-F bond feel repulsion due to 3 lone pairs on each F. dear dont generalize last point
