The highest energy occupied molecular orbital in the C-C bond of the C2 molecule is?
Butoxors [25]

The highest energy occupied molecular orbital in the C-C bond of the C₂ molecule is 2pπ orbitals.

<h3>What is Molecular Orbital Theory?</h3>

According to this theory,

  • Molecular orbitals are formed by intermixing of atomic orbitals of two or more atoms having comparable energies
  • The number of molecular orbitals formed is equal to the number of atomic orbitals combined.
  • The shape of molecular orbitals formed depends on the type of atomic orbitals combined
  • Only atomic orbitals having comparable energies and the same orientation can intermix
  • Bonding M.O. is formed by the additive effect of atomic orbitals and thus, has lower energy and high stability.
  • Antibonding M.O. is formed by the subtractive effect of atomic orbitals and thus, has higher energy and low stability.
  • Bonding M.O. is represented by \sigma, \pi, \delta while Antibonding M.O. is represented by \sigma^*, \pi^*, \delta^*\\

if a sample of gas at 25.2 c has a volume of 536mL at 637 torr, what will its volume be if the pressure is increased to 712 torr
nignag [31]
Considering ideal gas:
PV= RTn

T= 25.2°C = 298.2 K

P1= 637 torr = 0.8382 atm

V1= 536 mL = 0.536 L

:. R=0.082 atm.L/K.mol

:. n= (P1V1)/(RT) = ((0.8382 atm) x (0.536 L))/
((0.082 atmL/Kmol) x (298.2K))

:. n= O.0184 mol

Then,
P2= 712 torr = 0.936842 atm

V2 = RTn/P2 = [(0.082atmL/
Kmol) x (298.2K) x (0.0184mol) ]/(0.936842atm)

:.V2 = 0.4796 L
OR
V2 = 479.6 ml
