Identify the wrong statement from the statements given below.

Answer»

Geometrical structwe of `BrF_(5)` is square PYRAMIDAL.
Bond order and Bond energy of a molecule are directly related
H-O-H bond angle in water molecule is `104^(@).30'` because O atom is `sp^(3) ` hybridized.
Strength of `sigma` bond is related to the magnitude of overlap of ATOMIC orbitals.

Solution :H-O-H bond angle in water molecule is `104^(@).30.` because O atom is `sp^(3) ` hybridized.
This statement is wrong. As .O. has `sp^(3)` hybridization but due to repulsion between lone PAIR on OXYGEN bond angle decrease from `109^(@)28.` and become `104^(@)30.` .
