Question

The incorrect statement among the following is (A) Reducing character of hydrides of group 15 increases down the group (B) Basicity of hydrides of group 15 increases down the group (C) Phosphorus and arsenic can form p π -d π bond but not nitrogen (D) NCl5 does not exist

Tardigrade Admin · Accepted Answer

Hydrides of group 15 are basic due to their ability to donate lone pair of electrons. On moving down the group, the size of atom increases and consequently charge density decreases. Therefore the lone pair is less available for donation. Hence basicity decreases down the group.

Q. The incorrect statement among the following is

Reducing character of hydrides of group 15 increases down the group

Basicity of hydrides of group 15 increases down the group

Phosphorus and arsenic can form $p π - d π$ bond but not nitrogen

$NC l_{5}$ does not exist

Hydrides of group 15 are basic due to their ability to donate lone pair of electrons. On moving down the group, the size of atom increases and consequently charge density decreases. Therefore the lone pair is less available for donation. Hence basicity decreases down the group.
