Witryna1 dzień temu · Yes, water (H2O) is polar. This is because of the bent shape of the water molecule due to which there is an unequal charge distribution over the atoms of hydrogen and oxygen involved in the molecule of water. Therefore, the water molecule possesses a net dipole moment. Being a tasteless and odorless liquid compound at … WitrynaAnswer: HCl is polar covalent compound as the chloride ion is more electronegative than hydrogen ion. So chloride ion carries partial negative character while hydrogen carries partial positive character. Covalent character is shown by HCl as the atoms of hydrogen and chlorine share their electrons with each other.

Witryna13 gru 2024 · Hydrogen is less electronegative than some metals and more electronegative than many others.

You can predict whether a molecule will be polar or nonpolar by looking at the type of chemical bonds formed between the atoms of the elements. If there is a significant difference between the electronegativity values of the atoms, the electrons won't be shared equally between the atoms. In other words, the … elarise.com reviewsWitrynaThe electronegativity value for carbon (C) and hydrogen (H) is 2.55 and 2.1 respectively, so the difference in their electronegativity values is only 0.45 (<0.5 criteria); the electrons are thus equally shared between carbon and hydrogen.
