Why B_(2) is paramagnetic in nature while C_(2) is not? |
|
Answer» Solution :The molecular ORBITAL ELECTRONIC configuration of both `B_(2) and C_(2)` are: `B_(2):[sigma1s]^(2)[sigma^(**)1s]^(2)[sigma^(**)2s]^(2)[sigma^(**)2s]^(2)[pi2p_(x)]^(1)[pi2p_(y)]^(1)` `B_(2):[sigma1s]^(2)[sigma^(**)1s]^(2)[sigma^(**)2s]^(2)[sigma^(**)2s]^(2)[pi2p_(x)]^(2)[pi2p_(y)]^(2)` SINCE `B_(2)` has two unpaired electrons, therefore, `B_(2)` is paramagnetic. `C_(2)` has no unpaired electron, therefore, `C_(2)` is diamagnetic. |
