IE(Be)>IE(B) Thus, Li < B < Be < C is the order of first ionisation energy

Q. Which of the following order is incorrect?

(a) $N H_{3} < P H_{3} < A s H_{3}$ Acidic character

(b) $L i < B e < B < C$ First ionisation energy

(c) $A l_{2} O_{3} < M g O < N a_{2} O < K_{2} O$ Basic character

(d) $L i^{+} < N a^{+} < K^{+} < C s^{+}$ Ionic character

$I E_{(B e)} > I E_{(B)}$ Thus, $L i < B < B e < C$ is the order of first ionisation energy


(a)	$N H_{3} < P H_{3} < A s H_{3}$	Acidic character
(b)	$L i < B e < B < C$	First ionisation energy
(c)	$A l_{2} O_{3} < M g O < N a_{2} O < K_{2} O$	Basic character
(d)	$L i^{+} < N a^{+} < K^{+} < C s^{+}$	Ionic character
