Answer: The angle between the carbon-chlorine bonds in phosgene will be 120°
Explanation: Formula used to calculate the hybridization:
[tex]{\text{Number of electron pairs}} =\frac{1}{2}[V+N-C+A][/tex]
where,
V = number of valence electrons present in central atom i.e. carbon = 4
N = number of monovalent atoms bonded to central atom = 2
C = charge of cation = 0
A = charge of anion = 0
For [tex]COCl_2[/tex]
[tex]{\text{Number of electron pairs}} =\frac{1}{2}[4+2-0+0]=3[/tex]
The number of electron pairs are 3 which means that the hybridization will be [tex]sp^2[/tex] and the electronic geometry of the given molecule will be trigonal planar.
The bond angle in this electronic geometry is 120°
The structure of phosgene is attached below.
