Explanation:
The incorrect example among the given compounds formed by chemical bonding is option D, which states that NH3 is a molecule that is V-shaped with a bond angle of 104.5 degrees.
Reason:
The correct bond angle for NH3 is 107 degrees, not 104.5 degrees as mentioned in option D.
Details:
Let's analyze each option to understand why option D is incorrect:
a) A molecule with central atom devoid of octet - BF3:
BF3 is a molecule in which boron (B) is the central atom and is surrounded by three fluorine (F) atoms. Boron has only six electrons in its valence shell, so it does not have an octet. This is a valid example of a molecule with a central atom devoid of an octet.
b) A molecule with linear shape - CO2:
CO2 is a molecule in which carbon (C) is the central atom and is double-bonded to two oxygen (O) atoms. The shape of CO2 is linear, with a bond angle of 180 degrees. This is a valid example of a molecule with a linear shape.
c) A non-polar covalent compound between two different atoms - CH4:
CH4 is a molecule in which carbon (C) is the central atom and is surrounded by four hydrogen (H) atoms. The electronegativity difference between carbon and hydrogen is very small, so the C-H bonds are considered non-polar covalent. This is a valid example of a non-polar covalent compound between two different atoms.
d) A molecule which is V-shaped with a bond angle 104.5 - NH3:
NH3 is a molecule in which nitrogen (N) is the central atom and is surrounded by three hydrogen (H) atoms. The shape of NH3 is trigonal pyramidal or V-shaped, with a bond angle of approximately 107 degrees. The given bond angle of 104.5 degrees is incorrect. Therefore, option D is incorrect.
Overall, the incorrect example among the compounds formed by chemical bonding is option D, NH3, due to the incorrect bond angle mentioned.
