Question

Rank the following elements in order in terms of the character of the bond that they form with hydrogen, from most polar to least:

F,I,Br,Cl

Rank the following bonds in order of bond length, from longest to shortest.

1. XO3-w where X is a hypothetical element that can expand its octet and forms 5 bonds total between the 3 Os

2. XO3 where X is a hypothetical element that can expand its octet and forms 2 bonds to each of the 3 Os

3. XO3-ywhere X is a hypothetical element that can expand its octet and forms 1 bond with each O

4. XO3where X is a hypothetical element that can expand its octet and forms 4 bonds total between the 3 Os

1. XO3-w where X is a hypothetical element that can expand its octet and forms 5 bonds total between the 3 Os

Explanation / Answer

XO3-y> XO3 >XO3-w > XO3 (where X is a hypothetical element that can expand its octet and forms 2 bonds to each of the 3 Os)
