What are hybridisation states of each carbon atom in the following compound : C6H6

Answer

B

Explanation

`2 C(s)+3H_(2)(g)rarrC_(2)H_(6)(g)`
`Delta_(f)H^(@)=[(2xxDelta_("sub")H(C,s)),(3xxB.E.(H-H))]`
`-[(B.E.(C-C)),(+6xxB.E.(C-H))]`
`-85 = 2xx718 + 3 xx 436 - (x+6y)`
`x + 6y = 2829" ...(1)"`
Similarly, for `C_(3)H_(8)(g)`
`2x+8y= 4002 " ...(2)"`
from Eqs. (1) and (2)
x = 345 kJ/mol, y = 414 kJ/mol
