question 24 (6 points)
for hso4 ion
a) draw the lewis structure diagram
b) predict the shape around the central atoms
c) molecular polarity
d)vsepr notation
e) indicate the bond angle
f) predominant intermolecular force

Explanation:

a) Lewis structure: Central S bonded to 2 O (double bonds), 2 O (single bonds; one O has H attached, one has a negative charge). All O have lone pairs to satisfy octet.
b) Central S has 4 bonding domains (no lone pairs), so shape is tetrahedral.
c) Polar bonds (S-O, O-H) are asymmetrically arranged, making the ion polar.
d) VSEPR notation: AX₄ (A=central S, X=4 bonding domains).
e) Tetrahedral bond angle is ~109.5°.
f) As a charged ion, the predominant intermolecular force is ion-dipole (when interacting with polar molecules) or ionic interactions (with oppositely charged ions).

Answer:

a) Lewis structure: S at center, double bonds to 2 O, single bonds to 1 O-H and 1 O⁻ (lone pairs on all O atoms)
b) Tetrahedral
c) Polar
d) AX₄
e) ~109.5°
f) Ion-dipole force (or ionic interactions)
