View answer and explanation
Correct option: D
H2PO<H2Te<H2Se<H2S<H2O{H_2}PO < {H_2}Te < {H_2}Se < {H_2}S < {H_2}O
Option D (H2PO<H2Te<H2Se<H2S<H2O{H_2}PO < {H_2}Te < {H_2}Se < {H_2}S < {H_2}O) is correct because thermal stability decreases down the group due to decreasing bond dissociation energy, with water being an exception due to strong hydrogen bonding.
