Ans: In PCl5, Phosphate is the central atom and the molecule has a trigonal bipyramidal geometry. The 5 chlorine atoms are bonded to phosphorus atom. Of the five chlorine atoms, three are positioned at the equatorial position and the remaining two in the axial positions.
The bond angles are:
For the equatorial chlorine atoms they are in a trigonal plane, and the angle of Cl-P-Cl is 120 degrees.
For the other axial chlorine atoms they are above and below the trigonal plane and the angle of Cl-P-Cl is 90 degrees.
When nitrobenzene is treated with Br2 in the presence of FeBr3, m-bromo nitrobenzene is formed as a major product. The statement(s) related to this m-isomer is/are
The correct increasing order for bond angles among \( \text{BF}_3, \, \text{PF}_3, \, \text{and} \, \text{CF}_3 \) is:
The Valence Shell Electron Pair Repulsion Theory abbreviated as VSEPR theory is based on the premise that there is a repulsion between the pairs of valence electrons in all atoms, and the atoms will always tend to arrange themselves in a manner in which this electron pair repulsion is minimalized.
