we see an example of Quintuple bonds, I was wondering what the hybridization of this would be?

[hermanntrude]

the hybridisation belongs to the respective atoms. That depends on what other bonds the atoms are involved in. The quintuple bond consists of a sigma bond, two pi bonds and two delta bonds
