why does water attract plorar molecules and repel nonpolar ones?

Question

if a water molecule has no netcharge, then why does it atract polar molecules and repel nonpolar ones?

Answer 1

Water molecules are polar, even though they have no net charge. The hydrogen end of the water molecule is more positive, and the oxygen end is more negative.

Answer 2

Water itself is somewhat polar. It has a positive charge at one and and a negative at the other. In a glass of water the positives and negatives of water are content to be attracted to each other. If you introduce another polar molecule such as ethanol or normal butanol, perhaps they have a higher affinity for the positives and negatives than water has for itself. So there will some degree of miscibility. Now if you add turpentine or mineral spirts to that glass of water there will be a separation. These solvents are almost completely nonpolar and will not interact with water unless forced with stirring.

Answer 3

because water is polar, and if you know anything its that like goes with like and repels non-like. Water has a charge essentially, and nonpolar molecules do not, so when those nonpolar molecules get wind of the charge they repel.

Answer 4

The special qualities of water are down to the oxygen atom. Oxygen has 8 electrons. In water a total of 4 electrons are used for bonding with the hydrogen atoms. This leaves 4 electrons which are termed as 'free radicals'. These spare electrons attract the positive end of other polar molecules. The spare electrons in oxygen are also responsible for the blue tinge in water.

Answer 5

No, the precious ends of water molecules charm to the detrimental ends of different polar molecules, and the detrimental ends of water molecules charm to the precious ends of different polar molecules. the reason oil and water do not mixture is because oil is nonpolar and would not artwork at the same time nicely with polar water molecules.

Answer 6

hi
polar atract polar , becouse posetive charge combine or atract or connect with negetive charge and negetive charge combine or atract or connect with posetive charge (+ with -) & (- with +)
H2O =2 H+ & O-
and becouse of nonpolar has not charge

thanks
