The compound CBr4, also known as carbon tetrabromide, is a covalent compound. This is because it is formed by the sharing of electrons between carbon (C) and bromine (Br) atoms.
In CBr4, carbon shares its four valence electrons with four bromine atoms, each of which contributes one electron to form a covalent bond. This sharing of electrons allows each atom to achieve a stable electron configuration, similar to that of noble gases.
Ionic compounds, on the other hand, are formed by the transfer of electrons from one atom to another, resulting in the formation of positively and negatively charged ions. Since CBr4 involves electron sharing rather than electron transfer, it is classified as a covalent compound.
In summary, CBr4 is a covalent compound due to the shared electrons between carbon and bromine atoms, which allows each atom to achieve stability.
