The measured dipole moment of HCl is 1.03 D, while the value calculated for 100% ionic character is 6.12 D. The percent ionic character of the H-Cl bond is about:

Answer: 17%.

A 10%
B 17%
C 33%
D 50%

Correct answer: B. 17%

Explanation: Percent ionic character = (observed/ionic) x 100 = (1.03/6.12) x 100, which is approximately 17%.

VSEPR theory predicts molecular shape from the number of bonding and lone electron pairs around the central atom.

Concept context

Understand how atoms join to form molecules. Covers ionic and covalent bonding, VSEPR theory, hybridization (sp, sp², sp³), molecular orbital theory, bond polarity, and intermolecular forces like hydrogen bonding.
