B2 is a known molecule in gas phase, although not very stable, whose existence has been predicted in terms of MOT because it has a Bond Order greater than zero (in the case of B2, the bond order is 1). ZM WITH ME

As we know,

Bond order = 1/2(no of bonding electron - no of antibonding electron)

And as no of anti-bonding electron can never be more than no of bonding electron so bond order can never be negative.

Explanation:this is correct

check for the pregnancy rating of drug. if its class c or d see if other alternatives

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
