Shapes of Molecules
Example 4- Phosphorus Chloride (PCl₅)
Around the central P atom: 5 bonding pairs, 0 lone pairs
Takes 2 bonding angles: 90° between atoms around equator & atoms of axis; 120° between atoms at equator (360÷3) such that the shape of molecule formed is TRIGONAL BIPYRAMID.
•Example 5- Sulphur Fluoride (SF₆)
Around the central S atom: 6 bonding pairs, 0 lone pair
Bond angle is 90° (360÷4) such that the shape of molecule formed is OCTAHEDRAL
You finish both part 1 & 2!
Excellent Work~
