Hint: The molecular geometry of a molecule gives the general shape, bend angles, Torsional angles, bond lengths etc. the Propertius like polarity, reactivity, Colour, state of matter etc. can be determined by knouting the molecular geometry of the molecule.
Complete step by step answer: The molecular geometry is determined with the help of some special techniques named as spectroscopic and diffraction methods, example: , Raman spectroscopy etc.
The geometry of individual molecules is discussed below:-
-
According to , Theory, geometry of is trigonal bi pyramidal.
-
According to Theory geometry of is trigonal pyramidal.
-
According to Theory geometry of is trigonal pyramidal.
-
According to Theory geometry of is trigonal planar.
or Boron trifluoride is an organic compound with a pungent smell, it is a colorless, poisonous gas.
does not have any lone pair, the three atoms are arranged around central Boron at a bond angle of and bond length of .
Many other molecules such as formaldehyde sulfur trioxide , phosgene ozone etc. have similar trigonal planar geometry.
Hence, the correct option is
Note: is a short form of the valence shell electron pair repulsion theory. This theory. Can predict the geometry of many molecules, especially those belonging to the p – block, in theory, the geometry of a molecule atom. The geometry of a molecule depends upon the number of valence shell electrons around the central atom.
The pairs of electrons try to occupy minimum repulsion and maximal distance orientation in space.
