Question

the orientation of electron pairs and shape of molecule ate different in
1) BeCl2
2) H2O
3) BCl3
4) CCl4​

Answer 1

the orientation of electron pairs and shape of molecule are different in Becl2

Answer 2

Answer:

The orientation of electron pairs and the shape of the molecule are different in the H₂O molecule.

Explanation:

• BeCl₂ molecule has two bond pairs and no lone pairs. The type of hybridisation in the BeCl₂ molecule is sp hybridisation. Thus, it is a linear molecule.

• BCl₃ possess three bond pairs and zero lone pairs. The molecule has sp² hybridisation. The bond angle is 120° and the shape of the molecule is trigonal planar.
• CCl₄ has a tetrahedral shape as it possesses four bond pairs and no lone pairs. The hybridisation is sp³ hybridisation and the bond angle is 109°28'.
• Two lone pairs and two bond pairs are present in the H₂O molecule. The shape of the molecule gets distorted when lone pair of electrons are present. The shape of the H₂O molecule is angular or bent shape due to the two lone pairs present. The geometry is tetrahedral.

Thus, the orientation of electron pairs and the shape of the molecule are different in the H₂O molecule.
