In a polar nitrogen trifluoride, nf3 molecule, nitrogen and fluorine atoms share electrons. the fluorine atoms have a stronger attraction for electrons than the nitrogen atom has. what can be determined from the molecule's polarity? a. it has polar bonds and is symmetric. b. it has ionic bonds and is symmetric. c. it has polar bonds and is asymmetric. d. it has nonpolar bonds and is asymmetric.

Option C

In molecule, nitrogen has 5 valence electrons and F has 7 valence electron, 3 electrons of nitrogen are shared with 3 Fluorine atoms and 2 electrons are left on nitrogen atom as lone-pair.

The structure of  will be pyramidal.

Fluorine is more electronegative than nitrogen, due to this high electronegativity difference the N-F bond is polar in nature. There is net dipole moment in  molecule thus, it is asymmetric in nature.

The structure of is in the attached file.

Therefore, it has polar bonds and it is asymmetric.

what type of charge does it have? negative

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
