Question

Using molecular orbital theory predict the correct decreasing bond order of the following species 1 . O 2 + 2 . O 2 - 3 . O 2 2 - 4 . O 2 2 +, 1 > 2 > 3 > 4, 4 > 1 > 2 > 3, 4 > 1 > 3 > 2, 1 > 4 > 2 > 3

MARKS App · Accepted Answer

Bond order = no.of bonding e ¯ - no. of anti bonding e ¯ 2 Bond orders of O 2 + , O 2 - , O 2 2 - and O 2 2 + are respectively 2.5, 1.5, 1 and 3 Hence O 2 2 + has max bond order is O 2 2 + > O 2 + > O 2 - > O 2 2 -
