Question

BF3 and NF3 both molecules are covalent, but BF3 is non polar and NF3 is polar. Its reason is (A) In uncombined state boron is metal and nitrogen is gas (B) B - F bond has no dipole moment whereas N - F bond has dipole moment (C) The size of boron atom is smaller than nitrogen (D) BF3 is planar whereas NF3 is pyramidal

Tardigrade Admin · Accepted Answer

BF3 is planar while NF3 is pyramidal due to the presence of lone pair of electron on nitrogen in NF3.

Q. $B F_{3}$ and $N F_{3}$ both molecules are covalent, but $B F_{3}$ is non polar and $N F_{3}$ is polar. Its reason is

In uncombined state boron is metal and nitrogen is gas

$B - F$ bond has no dipole moment whereas $N - F$ bond has dipole moment

The size of boron atom is smaller than nitrogen

$B F_{3}$ is planar whereas $N F_{3}$ is pyramidal

$B F_{3}$ is planar while $N F_{3}$ is pyramidal due to the presence of lone pair of electron on nitrogen in $N F_{3}$ .

Q. BF3​ and NF3​ both molecules are covalent, but BF3​ is non polar and NF3​ is polar. Its reason is

In uncombined state boron is metal and nitrogen is gas

B−F bond has no dipole moment whereas N−F bond has dipole moment

The size of boron atom is smaller than nitrogen

BF3​ is planar whereas NF3​ is pyramidal

BF3​ is planar while NF3​ is pyramidal due to the presence of lone pair of electron on nitrogen in NF3​.

Q. $B F_{3}$ and $N F_{3}$ both molecules are covalent, but $B F_{3}$ is non polar and $N F_{3}$ is polar. Its reason is
