1Debye =10-18 esucm As shown in the image all the vectors in NH 3 are in the same direction and in opposite direction in the case of NF 3. so the resultant dipole moment will be more for NH 3. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/b64c81177982590924f219f57d251cfc-.png" />

Q. What is the correct dipole moment of $N H_{3}$ and $N F_{3}$ respectively?

$4.90 \times 1 0^{- 30} C m$ and $0.80 \times 1 0^{- 30} C m$

$0.80 \times 1 0^{- 30} C m$ and $4.90 \times 1 0^{- 30} C m$

$4.90 \times 1 0^{- 30} C m$ and $4.90 \times 1 0^{- 30} C m$

$0.80 \times 1 0^{- 30} C m$ and $0.80 \times 1 0^{- 30} C m$

1Debye $= 1 0^{- 18}$ esucm
As shown in the image all the vectors in $N H_{3}$ are in the same direction and in opposite direction in the case of $N F_{3}$ .
so the resultant dipole moment will be more for $N H_{3}$ .

Q. What is the correct dipole moment of NH3​ and NF3​ respectively?

4.90×10−30Cm and 0.80×10−30Cm

0.80×10−30Cm and 4.90×10−30Cm

4.90×10−30Cm and 4.90×10−30Cm

0.80×10−30Cm and 0.80×10−30Cm
