`PH_(3)` is a weaker base than `NH_(3)` - Explain.

Both PH_(3) and NH_(3) are Lewis bases, but basic strength of PH_(3) is less than that of NH_(3) . Explain.

Account for the following : (a) (CH_(3))_(2)NH is a stronger base than NH_(3) (b) CH_(3)CH_(2)NH_(2) is more basic than CH_(3)CONH_(2) (c) Aniline is less basic than Ethyl amine (d) On sulphonation of aniline, p-amino benzene sulphonic acid is formed.

(A) NH_(3) is a better reducing agent than PH_(3) (R ) NH_(3) is weaker lewis base when compared to PH_(3)

PH_(3) has lower boiling point than NH_(3) . Why ?

(A) Phenol undergoes Kolbe's reaction but not ethanol. (R) Phenoxide ion is a weaker base than ethoxide ion.

PH_(3) can be obtained by :

Bond angle in "PH"_(4)^(" "+) is higher than that in "PH"_(3) . Why ?

NH_(3) gas is liquified more easily than N_(2) . Hence :

The electronegativity difference between N and F is greater than that between N and H yet the dipole moment of NH_(3) (1.5 D) is larger than that of NF_(3) (0.2D) This is because

NH_(3) has a much higher boiling point than PH_(3) because
