Question -
Answer -
BeCl2:
The central atom has no lone pair and thereare two bond pairs. i.e., BeCl2 is of the type AB2.Hence, it has a linear shape.
BCl3:
The central atom has no lone pair and thereare three bond pairs. Hence, it is of the type AB3. Hence, it istrigonal planar.
SiCl4:
The central atom has no lone pair and thereare four bond pairs. Hence, the shape of SiCl4 is tetrahedralbeing the AB4 type molecule.
AsF5:
The central atom has no lone pair and thereare five bond pairs. Hence, AsF5 is of the type AB5.Therefore, the shape is trigonal bipyramidal.
H2S:
The central atom has one lone pair and thereare two bond pairs. Hence, H2S is of the type AB2E. Theshape is Bent.
PH3:
Thecentral atom has one lone pair and there are three bond pairs. Hence, PH3 isof the AB3E type. Therefore, the shape is trigonal pyramidal.
