Question

The boiling points of the following hydrides follow the order of (A) SbH3 > NH3 > AsH3 > PH3 (B) NH3 > AsH3 > PH3 > SbH3 (C) SbH3 > AsH3 > PH3 > NH3 (D) NH3 > PH3 > AsH3 > SbH3

Boiling point of NH3 is high due to intermolecular hydrogen bonding. In others it varies directly with molecular weight of molecule due to increased van der Wall’s force. This force is least in PH3 highest in SbH3.

Q. The boiling points of the following hydrides follow the order of

$S b H_{3} > N H_{3} > A s H_{3} > P H_{3}$

$N H_{3} > A s H_{3} > P H_{3} > S b H_{3}$

$S b H_{3} > A s H_{3} > P H_{3} > N H_{3}$

$N H_{3} > P H_{3} > A s H_{3} > S b H_{3}$

Boiling point of $N H_{3}$ is high due to intermolecular hydrogen bonding. In others it varies directly with molecular weight of molecule due to increased van der Wall’s force. This force is least in $P H_{3}$ & highest in $S b H_{3}$ .

Q. The boiling points of the following hydrides follow the order of

SbH3​>NH3​>AsH3​>PH3​

NH3​>AsH3​>PH3​>SbH3​

SbH3​>AsH3​>PH3​>NH3​

NH3​>PH3​>AsH3​>SbH3​

Boiling point of NH3​ is high due to intermolecular hydrogen bonding. In others it varies directly with molecular weight of molecule due to increased van der Wall’s force. This force is least in PH3​ & highest in SbH3​.

$S b H_{3} > N H_{3} > A s H_{3} > P H_{3}$

$N H_{3} > A s H_{3} > P H_{3} > S b H_{3}$

$S b H_{3} > A s H_{3} > P H_{3} > N H_{3}$

$N H_{3} > P H_{3} > A s H_{3} > S b H_{3}$

Boiling point of $N H_{3}$ is high due to intermolecular hydrogen bonding. In others it varies directly with molecular weight of molecule due to increased van der Wall’s force. This force is least in $P H_{3}$ & highest in $S b H_{3}$ .
