Vedclass · Answer

(A) $1$. $CO_2$ is linear and $BF_3$ is trigonal planar. Due to their symmetrical geometry,the net dipole moment is zero. This statement is correct.$2$. In $NH_3$,the dipole moments of $N-H$ bonds and the lone pair are in the same direction,leading to a higher net dipole moment. In $NF_3$,the dipole moments of $N-F$ bonds are in the opposite direction to the lone pair moment,resulting in a smaller net dipole moment. Thus,the dipole moment of $NF_3$ is lower than that of $NH_3$. This statement is incorrect.$3$. The dipole moment $\mu = q 	imes d$. Although the bond length of $HI$ is greater than $HCl$,the electronegativity difference in $HCl$ is much larger than in $HI$,making the charge separation $q$ significantly higher in $HCl$. Thus,$HI$ has a lower dipole moment than $HCl$. This statement is correct.

Identify the correct statements from the following. $(1)$ The dipole moment of $CO_2$ and $BF_3$ is zero. $(2)$ The dipole moment of $NF_3$ is higher than the dipole moment of $NH_3$. $(3)$ The dipole moment of $HI$ is lower than the dipole moment of $HCl$.
