What you have listed is the molecular formula, C6H4Cl2, the molecular formula is a multiple of the empirical formula in this case being C3H2Cl.
CCl6 doesn't exist. CCl4 and and C2Cl6 do however.
C2Cl6 (dichlorodifluoromethane) is a nonpolar molecule due to its symmetrical tetrahedral shape and the equal sharing of electrons between carbon and chlorine atoms. This results in no overall dipole moment, making it nonpolar.
It doesn't exist. The valence shell of oxygen (n = 2) does not have access to any d orbitals, so oxygen is unable to expand its octet to produce OF6. However, the compounds sulfur hexafluoride (SF6) and selenium hexafluoride (SF6) do exist because they have access to d orbitals in which they can form expanded octets. The hybridization of the central atom in SF6 and SeF6 is sp3d2.
Trimethylindium is extremely reactive towards oxygen and water. With low concentrations of oxygen (ppb to ppm to a few %), it immediately forms dimethylindium methoxide (Me2InOMe) as the first reaction product by insertion of O between In and C. With increased concentrations of oxygen (several %, atmospheric air or pure oxygen), it burns or explodes. Similar insertion reactions are expected with other elements of Group 16 (such as S, Se and Te) with highly vigorous outburst at higher concentrations of S, Se and Te. Trimethylindium reacts readily and vigorously with water to form Me2InOH and Methane (CH4) gas if the concentration of H2O is very small (upto 1000's ppm). With high concentrations of water (% level), trimethylindium can burn and often explode leaving behind In(OH)3, In2O3 as the final products. Extremely violent reactions of trimethylindium are also known with oxidizers (such as H2O2, KMnO4, HNO3, Bleach) and halogenated compounds (CCl4, CBrCl3, CBr2Cl2, CHCl3, C2Cl6 and halocarbon oils).

CH4 + 4Cl2 -----> CCl2 + 4HCl This is the current common method of tetrachloride synthesis, under heat and pressure, although another involves further chlorinating of chlorocarbons e.g. C2Cl6 + Cl2. Earlier methods used chloroform or disulphide, reacted with chlorine.
