Question
Ratio of P to s bonds in benzene
is-Solution
  In Benzene, C6H6, 6-Hydrogen bonds are bonded with 6 carbons with sigma bonds, 6 C-C atoms are bonded by sigma bonds in which 3 C-C atoms are bonded by 1 pi bond also. Thus, total number of bonds are- s -bonds (C-C) = 6; s -bonds (C-H) = 6; P -bonds (C-C) = 3 Total s -bonds= 12; total P -bonds= 3 Therefore, ratio of P to s bonds in benzene is 3/12 =1:4
