07. The p-BLOCK ELEMENTS (XII)
189220
Amongst \({H_2}O,\) \({H_2}S,\) \({H_2}Se\) and \({H_2}Te\) the one with the highest boiling point is
1 \({H_2}O\) because of hydrogen bonding
2 \({H_2}Te\) because of higher molecular weight
3 \({H_2}S\) because of hydrogen bonding
4 \({H_2}Se\) because of lower molecular weight
Explanation:
(a) \({H_2}O\) containing hydrogen bond.
07. The p-BLOCK ELEMENTS (XII)
189221
Among the hydrides formed by the group \(VI-A\) elements, only \({H_2}O\) has an abnormally low volatility (high boiling point). This is so because
1 \({H_2}O\) molecules are associated due to intermolecular hydrogen bonds
2 \({H_2}O\) is covalent in nature
3 The \(O - H\) bond in \({H_2}O\) is very strong
4 The electronegativity difference of \(H\) and \(O\) is very large
Explanation:
It’s Obvious.
