JEE MAIN - Chemistry (2024 - 4th April Morning Shift - No. 16)

The correct order of first ionization enthalpy values of the following elements is :

(A) O

(B) N

(D) F

(E) B

Choose the correct answer from the options given below :

$$\mathrm{A}<\mathrm{B}<\mathrm{D}<\mathrm{C}<\mathrm{E}$$

$$\mathrm{C}<\mathrm{E}<\mathrm{A}<\mathrm{B}<\mathrm{D}$$

$$\mathrm{E}<\mathrm{C}<\mathrm{A}<\mathrm{B}<\mathrm{D}$$

$$\mathrm{B}<\mathrm{D}<\mathrm{C}<\mathrm{E}<\mathrm{A}$$

Correct ionization enthalpy order :

$$\quad$$B < Be < O < N < F

or E < C < A < B < D
