Question 1

Place the following in order of decreasing bond length.

H-F

H-I

H-Br

◦ H-F > H-Br > H-I
◦ H-I > H-Br > H-F
◦ H-Br > H-F > H-I
◦ H-I > H-F > H-Br
◦ H-F > H-I > H-Br

Question 2

Place the following in order of decreasing XO bond length, where "X" represents the central atom in each of the following compounds or ions:
