In phosphorus trichloride (PCl₃), the phosphorus atom is the central atom surrounded by three chlorine atoms. Phosphorus has five valence electrons, and each chlorine atom forms a single bond with phosphorus, using three of its electrons. This leaves two electrons as a lone pair on the phosphorus atom. Therefore, there is one lone pair on the phosphorus in PCl₃.

How many lone pairs are on p in PCI3?
In phosphorus trichloride (PCl₃), the phosphorus atom has one lone pair of electrons. Phosphorus is in Group 15 of the periodic table and typically has five valence electrons. In PCl₃, it forms three bonds with chlorine atoms, using three of its valence electrons, leaving one lone pair.
How many lone pairs are on the P in PCl3?
One lone pair and three bonding chlorine pairs. General shape is tetrahedral and it's a trigonal pyramidal.
In PC 1 3 how many atoms bond to the central atom and how many lone pairs are there in it?
In PCl3 there are three bonds to the central atom (P) and one lone pair.. This can be worked out as follows. P has 5 valence electrons, shares three electrons with the chorine atoms (1 each) leaving 2 electrons on the P as a lone pair. In VSEPR theory this is an AX3E compound like ammonia.
What is the shape of the P atom in H2PO4?
It has 4 bonding pairs and no lone pairs so it has a tetrahedral shape.
WHY BOND ANGLE DECREASES WHEN WE MOVE FROM NH3 TO BH3?
The bond angle decreases from NH3 to BH3 primarily due to the difference in the presence of lone pairs and the types of bonding orbitals involved. NH3 has a lone pair on nitrogen, which exerts repulsion and pushes the hydrogen atoms closer together, resulting in a bond angle of about 107 degrees. In contrast, BH3 has no lone pairs on boron and adopts a trigonal planar geometry with bond angles of approximately 120 degrees. However, the effective repulsion from the empty p-orbitals in BH3 leads to a slight decrease in bond angle compared to the ideal trigonal planar geometry.
What is the Lewis structure for PCI3?

How do lone pairs in p orbitals affect the molecular geometry of a compound?
Lone pairs in p orbitals can affect the molecular geometry of a compound by influencing the bond angles and overall shape of the molecule. The presence of lone pairs can cause repulsion between electron pairs, leading to distortions in the molecule's geometry. This can result in deviations from the ideal bond angles predicted by the VSEPR theory, ultimately affecting the overall shape of the molecule.

What is the expected hybridization of the central atom of ICl3?
In icl3 central atom is iodine and its valency is 7 out of 7 electrons 3 electrons are in chemical bonding so 2 lone pairs are there. Hybridization = number of sigma bonds + number of lone pairs = 3 sigma bonds + 2 lone pairs = 5 = sp3d ( 1 s + 3 P + 1 d = 5 ).

Which out of the two following molecules is trigonal planar shape NF3 or PCL3?
NF3 has a trigonal planar molecular shape due to its three bonding pairs and one lone pair of electrons around the central nitrogen atom. In contrast, PCl3 has a trigonal pyramidal molecular shape because it has three bonding pairs and one lone pair of electrons around the central phosphorus atom.
How can one determine the number of pi electrons in a molecule?
To determine the number of pi electrons in a molecule, count the total number of electrons in the pi bonds and lone pairs that are part of the pi system. Pi electrons are the electrons involved in pi bonds, which are formed by the overlap of p orbitals. Lone pairs in conjugated systems also contribute to the number of pi electrons.
