Which of the following is incorrect ?

Options

  1. AI E 1 o f L i < I E 1 o f B e
  2. BI E 1 o f B e < I E 1 o f B
  3. CI E 1 o f L i > I E 1 o f N a
  4. DI E 1 o f H e > I E 1 o f N e

Correct answer

B. I E 1 o f B e < I E 1 o f B

Step-by-step solution

I E 1 o f B e > I E 1 o f B ; In B e removal occurs from 2 s ; In B it occurs from 2 p . More closer are subshell to nucleus more is I E .
