Explanation:
The lone pair of the electron on nitrogen atom present is arylamines is less available for protonation partly due to -I effect of a phenyl group and mostly due to resonance.
Hence aryl amines are weaker bases than alkyl amines.
Also, the secondary amines are a stronger base than the primary amines as the number of alkyl groups attached to the nitrogen atoms are more in secondary alkyl amines.

Where $A$ is $PCl^+_4$ while $B$ is $PCl^-_ 6$
Which of the following statement is INCORRECT :
$(I)$ $B$ to $A$ involvement of number of $d-$orbital in hybridization increases
$(II)$ $A$ to $B$ precentage of $p-$character in $P-Cl$ bond increases
$(III) $ Number of covalent bond in $A$ and $B$ are same
$(IV)$ $B$ is product of Lewis acid-base interaction which is associated with super octet molecule only
