Current Question (ID: 10549)

Question:

$\text{The element from group 15 that forms a strong bond with hydrogen is:}$

Options:

1. $\text{N}$ (Correct)
2. $\text{P}$
3. $\text{As}$
4. $\text{Sb}$

Solution:

$\text{HINT: Nitrogen is a highly electronegative element in group 15.}$ $\text{Explanation:}$ $\text{STEP 1: Nitrogen is a highly electronegative element. Down the group electronegativity decreases.}$ $\text{The decrease in electronegativity on going down the group is due to increase in size of the atoms and shielding effect of inner electron shells on going down the group.}$ $\text{STEP 2: Due to the electronegativity difference between hydrogen and nitrogen, nitrogen attracts the bonding electron toward itself in NH}_3 \text{ than towards phosphorus in PH}_3\text{.}$ $\text{Hence, the extent of hydrogen bonding in PH}_3 \text{ is very less as compared to NH}_3\text{.}$ $\text{STEP 3: Down the group the tendency to form strong bond with hydrogen decreases as the electronegativity of group 15 element is also decreasing down the group.}$
