The Scandinavian words (Old Norse mila, etc.) are from English. An ancient Roman mile was 1,000 double paces (one step with each foot), for about 4,860 feet, but there were many local variants and a modern statute mile is about 400 feet longer.
They are much weaker than ionic or covalent bonds and have a significant effect only when the molecules involved are close together (touching or almost touching). The figures show two arrangements of polar iodine monochloride (ICl) molecules that give rise to dipole-dipole attractions.Note: 1  Polar molecules have a partial negative end and a partial positive end. 2  The partially positive end of a polar molecule is attracted to the partially negative end of another.hey are much weaker than ionic or covalent bonds and have a significant effect only when the molecules involved are close together (touching or almost touching).

Those compounds which has partial positive and partial negative ends due to electronegative difference and there dnet dipole moment is not zero.for example: HCl,water. Those â¦ compounds whose net dipole moment or electronegativity differnce is zero are called as non polar.For example:H2,CH4,etc.olar The above answer is incorrect The correct answer is that AlCl3 is non polar, even though it is trigonal planar the atoms are spread symetrically making it non-polar! 7 people found this useful.
