JEE Main 2026 Chemistry question
Given below are two statements : Statement-I: The first ionization enthalpy of Cr is lower than that of Mn. Statement-II : The second and third ionization enthalpies of Cr are higher than those of Mn. In the light of the above statements, choose the correct answer from the options given below :
Answer: (2)
Solution
, . IE_1(Cr)<IE_1(Mn); IE_2(Cr)>IE_2(Mn) but IE_3(Cr)<IE_3(Mn), so Statement-II is false.
