What is the approximate Cl–Ca–F bond angle in the following molecule?

yes I missed something this, image was hidden and after looking at image I figured it out. Thanks.

To determine the approximate Cl–Ca–F bond angle in the molecule, we need to consider the molecular geometry around the central atom, Ca (calcium).

The molecule has a linear shape because the Cl–Ca–F atoms are all in a straight line. In a linear molecule, the bond angle is 180 degrees.

So, in this case, the approximate Cl–Ca–F bond angle is 180 degrees.

I'm not familiar with the compound CaClF but my best educated guess is that it's an ionic compound and has no bond angle. Or did you just forget to write the compound in the question?
