Question

1. The model shows water molecules

Answer 1

Answer:

The correct answer is A slight negative charge around the oxygen molecule and slight positive charge of the hydrogen atoms forms a polar molecule.

Explanation:

If we go through the chemical structure of water molecule ,we will see that a molecule consiat of 2 hydrogen atoms and one oxygen atom.As the electro negativity of the oxygen atom is far greater than that of hydrogen atom,the oxygen atom attract the bonding electron pair towards itself.This ultimately result in the generation of bond polarity.

  As oxygen attract the bonding electron pair towards itself the oxygen atom acquires slight negative charge .On the other hand the hydrogen atoms gets partial positive charge.

  Now the partial positive charged hydrogen atoms and partial negative charged oxygen atom forms a polar molecule known as water.
