React ethanol with PBr3 to from ethyl bromide. CH3Cl CCl4 CHCl3 NH3. CH4 has very low electronegativity difference between C & H ,so we should think of a dipole but here we have to see the tetrahedral structure of CH4 ,the resultant moment of the 4 bonds is zero as the moment from one bond nullifies that from three others. Since it has a tetrahedral geometry and the dipole moment is a vector quantity, the vector sum of all dipole moments would try to cancel out. Get answers by asking now. And for the others, it's all about electronegativity. 1 decade ago. Give reason. In $\ce{CHCl3}$ the dipole moment of the $\ce{C-Cl}$ bond is towards $\ce{Cl}$. The dipole moments of CCl4, CHCl3 and CH4 are in the order : (1) CH4 = CCl4 < CHCl3. The dipole moment of ethyl chloride is greater than vinyl chloride, because in vinyl chloride the moment due to resonance of lone pair on chlorine atom act in opposite direction of electronegative Cl-atom , which partially neutralized the actual dipole moment of vinyl chloride molecule and hence the experimental value of dipole moment slightly less than expected value . 4 years ago. Because CHCl3 is more polar than CH2Cl2 and CCl4. 2. Click hereto get an answer to your question ️ Regarding dipole moment of the following species. The molecule having largest dipole moment among the following is (a) CHI3 (c) CHCl3 (b) CH4 D) CCl4 my main doubt is- Which of the following molecules has polar bonds but has no net dipole?

The product of magnitude of charge on a molecule and the distance between two charges of equal magnitude with opposite sign is equal to dipole moment. 2- In CH2Cl2 dipole moment of H-H atoms and Cl-Cl atoms do not cancel each other because angle are not 180° so they are not linear. Since, although CCl4 has a tetrahedral configuration, bond dipoles in the reverse direction cancel out each other, so D=0 the dipole moment of CHCl3 is smaller than those of CH2Cl2 because if the bond dipole of the third C-Cl bond is compared to the corresponding bond dipoles of the other 2 C-Cl bond. asked Jan 26 in Chemistry by Sarita01 (53.4k points) jee main 2020; 0 votes.
