Question

Explain structure of water. Answer should not be less than 60 words.

Answer 1

water :- water form by combination of hydrogen and oxygen . e.g 2mole of hydrogen react with one mole of oxygen then form two mole of water .

H2O , in water electronegativity of O is more then electronegativity of H .so, here hydrogen bond occurs .due to hydrogen bond . one molecule of water is joined to four water molecule ( two with H-atom and two with O-atom) thus co-ordination of water molecule is four .

★ water is the polar , and having two lone pair of electrons .

by the way if we learn about angle between two bond of water and it's structure , then we should be used VESPR theory .
according to this , angle between two bond of water is less then 120° and structure is angular , V- type shape .

but shape of ice ( crystalline form of water) hexagonal closed packed structure .at low temperature and pressure . it have large voids that make ice less denser than water .

Answer 2

Answer:

water is formed by the combination of hydrogen and oxygen where there are the two atoms of hydrogen and one of oxygen
