Assertion: The formation of F_((g))^(-) from F_((g)) is exothermic, wh – InterviewSolution

1.	Assertion: The formation of F_((g))^(-) from F_((g)) is exothermic, whereas that of O_((g))^(2-) from O_((g)) is endotherrmic. Reason: The addition of second electron to a monovalent anion is difficult because both have the same charge and experience more repulsion.
Answer» If both ASSERTION and REASON are TRUE ANND the reason is the correct EXPLANATION of assertion If both assertion and reason are true but reason is not the correct explanation of assertion If assertion is true but the reason is false if assertion is false but the reason is true Answer :A
