Question

Quizplus · Accepted Answer

The increasing order of ionic character is based on the difference in electronegativity between the cation and anion. The larger the difference, the more ionic character the compound will have.

CsBr has the largest difference in electronegativity, followed by MgBr2, PBr3, and LaBr3. Therefore, CsBr has the most ionic character, while LaBr3 has the least.

The correct order of increasing ionic character is:

MgBr2 < PBr3 < LaBr3 < CsBr

Therefore, choice D is the best option, as it correctly arranges the compounds in this order.
