Which of the following species has two non bonded electron pairs on the central atom:a)TeCl4b)ClF3c)ICl2d)PCl3Correct answer is option 'D'. Can you explain this answer?

Question

Answer

Correct Ans. is (b). because 'cl' has 7 valence electron and out of 7 electron 3 electron take part in bonding and rest 4 electrons are called non bonded electron pair (loan pair) and 4 elec. =2 lon pair or non-bonded electron pair

Answer

B ans should be right..

Answer

They have both non electronic Pair
pcl3 and plc5 it can't bind central both of them due weak bond paring

Answer

Answer:

In order to determine which species has two non-bonded electron pairs on the central atom, we need to analyze the Lewis structures and electron pair geometries of each molecule.

Lewis Structures:
- TeCl4: This molecule consists of a central tellurium (Te) atom bonded to four chlorine (Cl) atoms. The Lewis structure for TeCl4 would have a single bond between Te and each Cl atom, resulting in a tetrahedral arrangement. There are no lone pairs on the central atom.
- ClF3: This molecule consists of a central chlorine (Cl) atom bonded to three fluorine (F) atoms. The Lewis structure for ClF3 would have a single bond between Cl and each F atom, as well as two lone pairs on the Cl atom. This structure results in a trigonal pyramidal arrangement.
- ICl2: This molecule consists of a central iodine (I) atom bonded to two chlorine (Cl) atoms. The Lewis structure for ICl2 would have a single bond between I and each Cl atom, as well as two lone pairs on the I atom. This structure results in a bent or V-shaped arrangement.
- PCl3: This molecule consists of a central phosphorus (P) atom bonded to three chlorine (Cl) atoms. The Lewis structure for PCl3 would have a single bond between P and each Cl atom, as well as one lone pair on the P atom. This structure results in a trigonal pyramidal arrangement.

Electron Pair Geometries:
- TeCl4: The tetrahedral arrangement of this molecule does not have any lone pairs on the central atom.
- ClF3: The trigonal pyramidal arrangement of this molecule has one lone pair on the central Cl atom.
- ICl2: The bent or V-shaped arrangement of this molecule has two lone pairs on the central I atom.
- PCl3: The trigonal pyramidal arrangement of this molecule has one lone pair on the central P atom.

Conclusion:
Among the given options, only ClF3 has two non-bonded electron pairs on the central atom. This is evident from the Lewis structure and electron pair geometry analysis. Therefore, the correct answer is option 'B'.
