How do you decide that molecule is symmetrical or unsym metrical?

Answer 1

A molecule is considered symmetrical if it exhibits symmetry elements such as planes of symmetry, centers of symmetry, or rotational symmetry. To determine this, one can analyze the molecular geometry and look for identical arrangements of atoms around a central point or axis. If the molecule can be divided into two mirror-image halves or rotated to match its original configuration without altering its appearance, it is symmetrical. Conversely, if no such symmetry can be found, the molecule is classified as unsymmetrical.
