Detailed explanation-1: -Carbon dioxide CO2 has polar bonds but is a nonpolar molecule. The structure of CO2 is linear. The individual bond dipoles cancel each other as they point in opposite direction and are equal in magnitude. Hence, the molecule is non polar with zero dipole moment.
Detailed explanation-2: -Methane forms a non-polar covalent bond. This is because there is a very small difference in the electronegativity of carbon and hydrogen. Thus they are going to share their electrons fairly equally.
Detailed explanation-3: -Hence, Carbon tetrachloride (CCl4) has non-polar covalent bonds between carbon and chlorine.
Detailed explanation-4: -Methane (CH4) is a non-polar hydrocarbon compound composed out of a single carbon atom and 4 hydrogen atoms. Methane is non-polar as the difference in electronegativities between carbon and hydrogen is not great enough to form a polarized chemical bond.
Detailed explanation-5: -Answer and Explanation: A) Methane is a nonpolar molecule due to the hydrogen bonds surrounding the central carbon atom in a three-dimensional configuration. The configuration as well as the structure renders the molecule to be nonpolar because the charges are distributed evenly across the molecule.
