Is carbon tetrachloride or sodium chloride conduct electricity in molten state?
Carbon tetrachloride (tetra-chloromethane, CCl4) is a NON-ionic fluid at room temperature, it is noncunducting fluid. NaCl is an ionic salt and will conduct electricity only when in molten state: then freely movable cations and anions are available.
Why does ethanol have a lower melting point than carbon tetrachloride?
Ethanol has weaker intermolecular forces (hydrogen bonding) compared to carbon tetrachloride (London dispersion forces), which results in a lower melting point for ethanol. The hydrogen bonding in ethanol requires less energy to break compared to the London dispersion forces in carbon tetrachloride, leading to an easier transition from solid to liquid state in ethanol.
What physical state is carbon tetrachloride at room temperature?
It is a liquid because at room temperature the molecular structure of the substance wants to expand. When the substance expands it goes from being a solid to a liquid. This expansion takes place when the room is at the commonly know "room temperature"
Why is the boiling point of carbon tetrachloride higher than chloroform?
Both chloroform and carbon tetrachloride have the same tetrahedral molecular geometry - there are 4 atoms attached to a central carbon atom. In chloroform, there are 3 chlorine atoms and 1 hydrogen atom. In carbon tetrachloride, all 4 atoms surrounding the central carbon are chlorine atoms. So the difference between the two is simply replacing the 1 hydrogen atom with another chlorine atom. In essence, by doing this, the density of the compound is increased, due to the increase in mass (remember a chlorine atom has an atomic mass of 35 and hydrogen an atomic mass of 1). The density of chloroform goes from 1.48 g/mL to 1.58 g/mL when you replace chloroform's hydrogen with that chlorine atom. Since there is an increased mass in a given volume (1 mL), it takes just a little more energy (thermal) to get carbon tetrachloride atoms from the liquid state to the gas state, which is why CCl4 has a bp of around 76 (while chloroform's bp was around 62). -------------------------------------------------------------------------------------------------------------- Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the B.pt. Chloroform has mostly dispersion forces and very, very weak dipole-dipole. The reason Carbon tetrachloride has a higher boiling point is because the combined effect of all the dispersion forces are stronger than the intermolecular forces that exist in chloroform. Dispersion forces increase with increasing molecular weight and # of electrons.
How can one determine the oxidation state of carbon in organic compounds?
To determine the oxidation state of carbon in organic compounds, one can count the number of bonds carbon forms with more electronegative elements like oxygen, nitrogen, or halogens. The oxidation state of carbon is equal to the number of bonds it forms minus the number of bonds it would form in a neutral state.
Does carbon tetrachloride conduct electricity when a solid?
No, carbon tetrachloride does not conduct electricity as a solid because it is a nonpolar molecule, meaning it lacks charged particles. In order to conduct electricity, a substance needs to have charged particles that can move to carry the electric current.

Is MnCl4 same as manganese TetraChloride?
Yes because tetra means four and there are four chlorine atoms present. However, the formula is normally written as Cl4Mn.
What is the number of carbon in methane?
In methane (CH4), carbon is in the 4- oxidation state.

What is the oxidation number of carbon in carbon dioxide?
The oxidation number of carbon in carbon dioxide (CO2) is +4. This is because oxygen typically has an oxidation number of -2, and since there are two oxygen atoms bonded to the carbon atom in CO2, the carbon atom must have an oxidation number of +4 to balance the charge.
What is the oxidation state of germanium in germanium tetrachloride?
The oxidation state of germanium in germanium tetrachloride (GeCl4) is +4. This is because each chlorine atom has an oxidation state of -1, and since there are four chlorine atoms in GeCl4, the oxidation state of germanium must be +4 to balance the overall charge of the compound.
What is the oxidation no of carbon in formaldehyde molecule is..?
The oxidation state of carbon in formaldehyde (CH2O) is +2. This is because oxygen typically has an oxidation state of -2, and there are only two atoms of oxygen present in formaldehyde. The overall charge of formaldehyde is zero, so the sum of the oxidation states must equal zero, leading to carbon having an oxidation state of +2.
What is the oxidation number of carbon in sucrose?
The oxidation number of carbon in sucrose is +4. In sucrose (C12H22O11), the carbon atoms are bonded to oxygen atoms through double bonds, causing the oxidation state of carbon to be +4.
