$NH_3$

Vedclass · Answer

(B) The polarity of a molecule is determined by its net dipole moment $(\mu)$.$1$. $H_2S$ has a bent geometry with a dipole moment of approximately $0.95 \ D$.$2$. $NH_3$ has a trigonal pyramidal geometry with a dipole moment of approximately $1.47 \ D$.$3$. $NF_3$ has a trigonal pyramidal geometry,but the electronegativity difference between $N$ and $F$ results in bond dipoles that partially cancel out,leading to a lower dipole moment of approximately $0.24 \ D$.$4$. $CHCl_3$ has a tetrahedral geometry with a dipole moment of approximately $1.01 \ D$.Comparing these values,$NH_3$ has the highest net dipole moment among the given options,making it the most polar molecule.
