Assuming that Hund's rule is violated the bond order and magnetic nature of the diatomic molecle `B_(2)` is

A

1 and diamagnetic

B

0 and diamagnetic

C

1 and paramagnetic

D

0 and paramagnetic

Text Solution

Verified by Experts

The correct Answer is:
C
`B_(2)(10):sigma_(1s)^(2)sigma_(1s)^(**2)sigma_(2s)^(2)sigma_(2s)^(**2)pi2p_(x)""^(1)pi2p_(y)^(1)`
`"Bond order"=(6-4)/(2)=1`
It is paramagnetic.
