  • #"Draw Lewis Structures of the molecule"#
  • #"Count no. of single bonds ,double bonds and triple bonds in it"#

#"Each SINGLE bond"->1 sigma " bond"#

#"Each Double bond"->1 sigma " bond" and 1 pi " bond"#

#"Each TRIPLE bond"->1 sigma " bond" and 2 pi " bond"#

Using this Rule we have here

#NO_2->2sigma and 1pi bond#

#O_2->1sigma and 1pi bond#

#C_2H_6->7sigma and "0 "pi bond#
