Answer:

Explanation:

Some of the elements of the third-period and periods below can have expanded octet because they have d- sub-level.

We have 2 possible answers. A and B. Because lodine and chlorine. Sulfur and phosphorous are in the 3d or lower periods.

In the compound P2S5, where P forms 5 bonds.

Iodine and chlorine do not have enough difference in electronegativity to form compound ICl7.

So, the answer is B.

Can an ether form hydrogen bonds in the same way as does an ester

belka [17]

Yes, an OH group from ethanol can form a hydrogen bond to the ether O atom in the same way as it can do so with the single-bonded O atom in the ester.

The O atom in the carbonyl group of the ester can also form H-bonds with ethanol.
