Explanation:
Center of symmetry ( or inversion point ) is a point from where any line drawn cuts the same atom or group of atoms in opposite direction at equal distances
A molecule has only one plane of symmetry!
• It is the point from where the distance of the same atom are equal and they are opposite to each other !!
• The condition is that the same atom must be opposite along the Center of symmetry !!
