Question g
State the shape of (i) the hydrogen chloride molecule (HCl), (ii) the water molecule (H2O).
Worked Solution & Example Answer:State the shape of (i) the hydrogen chloride molecule (HCl), (ii) the water molecule (H2O). - Leaving Cert Chemistry - Question g - 2013
Step 1
Step 2
(ii) the water molecule (H2O)
Answer
The shape of the water (H2O) molecule is bent or V-shaped. This occurs because of the two hydrogen atoms bonded to the oxygen atom with an angle of approximately 104.5 degrees, caused by the repulsion between the lone pairs of electrons in the oxygen atom.
