1、Arrange gaseous hudrogen halides in order of decreasing dipole moments and rationalize your order.
2、The dipole moments for the methyl halides are:
CH3F,1.82D; CH3Cl,1.94 D; CH3Br,1.79 D; CH3I,1.63 D
Explain.
答
1. HF>HCl>HBr>HI dipole moment is separation of charge between two atoms of a chemical bond related to the electronegativity of halogens and fluorine has the highest electronegativity, chlorine next, ...
