The shape of ' ' according to V.S.E.P.R theory-
Options:
Answer:
B
Solution:
To determine the shape of AsF₅ using VSEPR theory, we first find the number of valence electrons for the central atom, Arsenic (As). As is in Group 15, so it has 5 valence electrons. Each Fluorine (F) atom contributes 1 electron for bonding.
Total electrons around As = 5 (from As) + 5 (from 5 F atoms) = 10 electrons.
Number of electron pairs = electron pairs.
Since all 5 electron pairs are bonding pairs (no lone pairs), the steric number is 5. According to VSEPR theory, a molecule with 5 bonding pairs and 0 lone pairs adopts a trigonal bipyramidal geometry.
The correct answer is Trigonal bipyramidal.
