Question

an example of Triangular molecule​

Answer 1

Explanation:

Although the electron groups are oriented in the shape of a tetrahedron, from a molecular geometry perspective, the shape of NH3 is trigonal pyramidal. H2O is an example of a molecule whose central atom has four electron groups but only two of them are bonded to surrounding atoms.

Answer 2

Examples include BeH2 and CO2: A molecule with three electron groups orients the three groups as far apart as possible. They adopt the positions of an equilateral triangle-120° apart and in a plane. The shape of such molecules is trigonal planar.
