Question

What compound has the strongest hydrogen bonding at stp? 1) h2o 2)h2s 3)h2se 4)h2te

Lori Robel · Accepted Answer

The strongest hydrogen bond type is the one involving a bond between oxygen, nitrogen and fluorine, with a hydrogen atom. Since in the choices, only water shows a O-H bond, therefore this is the strongest hydrogen bonding. The answer is water.

Lori Robel · Answer

Option (1) is the correct answer.Explanation:Oxygen, sulfur, selenium and tellurium are all group 8 elements. As we go gown the group there will be decrease in electronegativity of atoms. Also, more is the electronegativity of an  atom more it will attract the electrons towards itself. This will result in the formation of partial charges on the combining atoms. Thus, the molecule becomes polar. Here, oxygen is the most electronargative out of the given options, so it will attract the electrons more towards itself. Hence, it will have the strongest hydrogen bonding at STP.

Lori Robel · Answer

Hydrogen compounds with O, F or N are the strongest at STP. Therefore, the answer out of these choices would be H2O, also known as water.

Lori Robel · Answer

1) H2O is the correct answer.
