Which of the following compounds is the weaker Brønsted acid?Select answer from the options belowH2OH2Te

The Brønsted acidity of a compound is determined by its ability to donate a proton (H+). In this case, we are comparing water (H2O) and hydrogen telluride (H2Te).

The acidity of hydrides (compounds of hydrogen with other elements) increases down a group in the periodic table. This is because as the size of the atom bonded to the hydrogen increases, the bond becomes weaker and more easily broken to release a proton.

Tellurium is below oxygen in the periodic table, meaning it is larger and forms a weaker bond with hydrogen than oxygen does. Therefore, H2Te is a stronger acid than H2O.

So, H2O (water) is the weaker Brønsted acid.
