Question:
Consider the phosphodichloride (PCl2-) anion.
Answer:
–> Central atom here is Phosphorus, the symbol is P
–> Lone pairs are around the central atom — 2
–> Ideal angle between the phosphorus-chlorine bonds — as it has bent or angular structure so ideal bond angle will be 109.4.
–> you have two nb pairs pushing on the bond pairs, so the angles will be smaller than 109.47. because of the two nb pairs.
