To know the no. of #sigma and pi" bonds" # the Lewis structure of the compound is to be drawn showing all single,double and triple bonds. In this structure

#" Each single bond is 1"sigma" bond"#

#" Each double bond is 1"sigma and 1 pi" bond"#

#" Each triple bond is 1"sigma and 2 pi" bond"#

Using the above information we get can the no. of #sigma and pi"bonds" # in the given structure.

#4" single bonds"->4sigma " bonds"#

#1" double bond"->1sigma and 1pi " bonds"#

#4" triple bond"->4sigma and 8pi " bonds"#

#color(red)("So we have total"->9sigma and 9pi " bonds here")#
