Water possesses the greatest dipole moment. Which has highest dipole moment CO2 or H2O? Due to the lone pair on oxygen, the structure of H2O is bent (according to the VSEPR theory), meaning that the vectors representing the dipole moments of each bond do not cancel out. Is the bent structure of water have dipole moment? Different molecules are described by the phrases linear molecules and bent molecules. The primary distinction between linear and bent molecular shapes is that linear molecules have atoms that are covalently bound, making a straight molecule, whereas bent molecules have atoms arranged in an angled bend. ![]() What is the difference between bent and linear shapes? The carbon dioxide molecule is linear because the two double bonds strive to get as far apart as possible.

The dipole moment value of 1.84D for H2O also confirms its angular shape.Ĭontinue Reading -> Why bond angle in NH3 is 107° while in H2O is 104.5°? Due to the greater repulsion of the lone pair, the two bond pairs are compressed together to an angle of 104.5, resulting in an angular or bent structure of H2O. In H2O, an oxygen atom is sp3 hybridized and the four sp3 hybrid orbitals are occupied by the two lone pairs of electrons. The two sp-hybrid orbitals are at an angle of 120 from each other, resulting in the linear shape of co2 The linear shape of co2 is also confirmed by the zero value of its dipole moment. In CO2, the carbon dioxide atom is sp- hybridized. Watch -> Dipole Moment Concept in Simple Words ( Urdu / Hind) CO2 and H2O structure on the basis of Hybridization CO2 Hybridization Consequently, H2O will have a bent structure with a bond angle of 104 degrees. H2O is an asymmetrical molecule with curved geometries these geometries have a particular dipole moment (1.84D) because the bond polarities do not cancel each other out. The molecule with symmetrical and linear geometries has zero dipole moment because vectors exist in nature and the dipole of distinct bonds cancels out.ĬO2 is symmetrical and possesses a dipole moment of zero.Therefore,it will be linear with a bond angle of 180 degrees. The dipole moment is equal to the product of the size of the positive or negative charge (q) and the distance between the charges (d).
