To assign a point group to a molecule, you first identify its symmetry elements such as rotation axes, mirror planes, and inversion centers. Then, use those elements to determine the point group using crystallographic tables or software. The resulting point group describes the overall symmetry of the molecule.

What is point group Dn?
Point group D_n is a type of symmetry group in chemistry and crystallography. It has a 2-fold rotational axis with n total symmetry elements, including reflections and rotations. The "D" indicates that there are perpendicular C2 axes in the group.
Which element has a higher melting point potassium in group 1A for calcium in group 1B?
Calcium, which is in Group 2 (not 1B, as there is no Group 1B), has a higher melting point than potassium, which is in Group 1. This is due to calcium being a metal with a higher atomic number and stronger metallic bonds compared to potassium, resulting in a higher melting point. Calcium's melting point is approximately 842°C, while potassium's is around 63.5°C.
What is the point group of dimethylbenzene?
Dimethylbenzene, commonly known as xylene, has several isomers, including ortho, meta, and para xylene. The point group of ortho-xylene is (D_{2h}), while meta-xylene belongs to the (C_{2v}) point group, and para-xylene is classified as (D_{2h}). The specific point group depends on the arrangement of the methyl groups on the benzene ring, affecting the symmetry elements present.
How melting and boiling point varied in a period?
Generally melting point and boiling point increase up to group 6 and then decrease.
What element has the highest melting point of its group?
The element with the highest melting point in its group is carbon. Specifically, graphite has the highest melting point among the carbon allotropes, which is higher than the melting points of other elements in its group.
