Why does a water molecule have a bent shape?

1 answer:

3 0

The 2 lone electron pairs exerts a little extra repulsion on the two bonding hydrogen atoms to create a slight compression to a 104obond angle. The water molecule is bent molecular geometry because the lone electron pairs, although still exerting influence on the shape, are invisible when looking at molecular geometry.

Answer : The correct option is, (D) double replacement reaction

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

$X+Y\rightarrow XY$

Decomposition reaction : A chemical reaction in which larger reactant decomposes to give two or more than two products.

It is represented as,

$AB\rightarrow A+B$

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

$A+BC\rightarrow AC+B$

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

$XY+AB\rightarrow XB+AY$
