Question

Observe the following statements:

$1$. The solubility of group V hydrides in water decreases from $N{H}_3$ to $Bi{H}_3$.
$2$. Phosphorous does not exhibit allotropy.
$3$. The stability of group V hydrides decreases from $N{H}_3$ to $Bi{H}_3$

The correct statement(s) is/are:

• A. $2$
• B. $1$ and $2$
• C. $1,2$ and $3$
• D. $1$ and $3$

Answer 1

Answer: (D)

$1$ and $3$

Phosphorous shows allotropy in the form of red phosphorous, black phosphorous, white phosphorous and red phosphorous. Hence, statement $2$ is incorrect.

Therefore, option $D$ is correct.
