Question

?assignmentProblemID 94293571 Resources e previous| 10 of 22 I next Part A PI3 Br2 is a nonpolar molecule. Based on this information, determine the I-P-I bond angle, the Br-P-Br bond angle, and the I-P-Br bond angle. Enter the number of degrees of the I-P-I, Br P-Br, and I-P-Br bond angles, separated by commas (e.g., 38,45,9e) Hints degrees Submit My Answers Give Up Part B Which statement best describes the polarity of CF212? Hints The molecule is always polar. The molecule is always nonpolar. Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar

Explanation / Answer

Part-A

I-P-I bond angles: 120º,Br-P-Br bond angles: 180º,I-P-Br bond angles: 90º

Hence the answer will be written as... 120°, 180°, 90°

Part-B

The molecule is always polar. As the structure is tetrahedral, and there is no possible way to cancel out the dipoles.

Hence , the first option is correct.
