Explanation:

Step1: Determine valence - electron of central atom for ClF₃

Chlorine (Cl) is the central atom in ClF₃. Cl has 7 valence electrons. Each F atom contributes 1 electron for bonding. So the total number of valence - electrons around Cl is 7+3 = 10, or 5 electron - pairs. According to VSEPR, 5 electron - pairs give a trigonal bipyramidal electron - domain geometry.

Step2: Determine lone - pairs in ClF₃

In ClF₃, there are 3 bonding pairs and 2 lone pairs. The presence of 2 lone pairs in the equatorial positions of the trigonal bipyramid gives a T - shaped molecular geometry.

Step3: Determine valence - electron of central atom for SeCl₆

Selenium (Se) is the central atom in SeCl₆. Se has 6 valence electrons and each Cl atom contributes 1 electron for bonding. So the total number of valence - electrons around Se is 6 + 6=12, or 6 electron - pairs. According to VSEPR, 6 electron - pairs give an octahedral electron - domain geometry.

Step4: Determine lone - pairs in SeCl₆

In SeCl₆, there are 6 bonding pairs and 0 lone pairs. So the molecular geometry is octahedral.
