Fluorine has low electron affinity than chlorine because of

Options

  1. Abigger radius of fluorine, less electron density
  2. Bsmaller radius of fluorine, high electron density
  3. Csmaller radius of chlorine, high electron density
  4. Dsmaller radius of chlorine, less electron density

Correct answer

B. smaller radius of fluorine, high electron density

Step-by-step solution

Fluorine has low EA than chlorine because of smaller size of fluorine and compact 2 p -orbital where interelectronic repulsion is more
