Along the periods in the p-block of the periodic table, which of the following statements accurately — Hydrogen Chemistry Question

💡 Solution & Explanation

Acidic character of hydrides increases from left to right across a period due to increasing electronegativity. $NH_3$ is the strongest Bronsted base among the period 2 p-block hydrides. $B_2H_6$ is electron-deficient and acts as a Lewis *acid*, not a base. The anomalous boiling points are correctly attributed to hydrogen bonding.
