Which of the following order is incorrec...

Which of the following order is incorrect?

Acid nature , `NH_(3) lt PH_(3) gt AsH_(3)`

`IE_(1)` , ` Li lt Be lt B lt C `

Basic nature , `Al_(2) O_(3) lt Mgo lt Na _(2) O lt K_(2)O`

Ionic radius : `Li^(+) lt Na^(+) lt K lt Cs^(+)`

Verified by Experts

The correct Answer is:

The correct `IE` order is `Li lt B lt Be lt C`. (Be is mores than `B` due to stable `ns^(2)` electronic configuration).

Which of the following orders is incorrect?

F gt N gt C gt Si gt Ga - non -metallic character

F gt CI gt O gt N-oxidising property

C lt Si gt P gt N -electron affinity value

None of these

`N lt O lt F-II^(nd)` ionization energy.

`Li^(+) gt Na^(+) gt K^(+) -` ionic radius in water.

`S gt Se gt O -` negative value of electron gain enthalpy

`Al_(2)O_(3) lt MgO lt K_(2)O -` basic character.
