Which one of the following molecule has inversion centre :
Answers
Answer:
molecule having centre of inversion are CO2, C2H4, N2O2, [Co(NH3)6]3+ etc.
Answer:
Molecules having centre of inversion are O₂, CO₂, XeF₆ etc.
Explanation:
A symmetry element is a geometrical entity like a geometrical plane, point, or axis on which symmetry operations are performed.
Symmetry operations: The operations performed on a molecule in a 3-D space, brings back the original molecule as it was before in the starting state.
Centre of inversion:
- It is represented by 'i'
- It is the simplest type of symmetry operation.
- It's element is a single point in a space.
- It is a centre point from which the structure is visibly identical in any of the two or more opposite directions.
For eg. In O₂ molecule,
- O-O, centre of inversion present in between the bond in O₂.
Other molecules having centre of inversion are CO₂, C₂H₄, N₂O₂, XeF₆ and benzene ( C₆H₆ ).
RESULT: Molecule having centre of inversion in which the centre point from which the structure of a molecule is visibly identical in any of the opposite directions are O₂, CO₂, N₂O₂ etc.
