so it does not matter which atom you attach the wedge and line broken all that matters is you placed the wedge and broken line in the set place based on the shape of the molecule. answer to your question carbon has four outer electron each are used in covalent bond to fluorine and chlorine so no lone pairs. another method is 4+2+2=8
4 bond available however they all used by cl2 and f2 therefore no one pairs. thank you for the help appreciate it a lot.
