Given below are two statements.
Statement I: Fluorine has the most negative electron gain enthalpy in its group.
Statement II: Oxygen has the least negative electron gain enthalpy in its group.
In the light of the above statements, choose the most appropriate answer from the options given below:
Text Solution
Verified by ExpertsThe correct answer is:
B
In halogens, Cl (not F) has the most negative electron-gain enthalpy ( 
is less negative due to very small size/e-e- repulsion). In group 16, O has the least negative value (small size, high repulsion).
