The basic strength of methyl substituted amines in aqueous solution in decreasing order is-
(A)`(CH_(3))_(3)N>CH_(3)NH_(2)>(CH_(3))_(2)NH`
(B)`CH_(3)NH_(2)>(CH_(3))_(2)NH>(CH_(3))_(3)N`
(C)`(CH_(3))_(2)NH>CH_(3)NH_2>(CH_(3))_(3)N`
(D)`(CH_(3))_(3)N>(CH_(3))_(2)NH>CH_(3)NH_2`

Arrange the following in decreasing order of solubility in water: (CH_(3))_(3)N, (CH_(3))_(2)NH, CH_(3)NH_(2)

Arrange the following in decreasing order of the basicity. CH_(2)=CHCH_(2)NH_(2),CH_(3)CH_(2)CH_(2)NH_(2),CH-=C CH_(2)NH_(2)

Arrange the following in increasing order of their basic strength: (i) C_(2)H_(5)NH_(2),C_(6)H_(5)NH_(2),NH_(3),C_(6)H_(5)CH_(2)NH_(2)and(C_(2)H_(5))_(2)NH (ii) C_(2)H_(5)NH_(2),(C_(2)H_(5))_2NH,(C_(2)H_(5))_(3)N,C_(6)H_(5)NH_(2) (iii) CH_(3)NH_(2),(CH_(3))_(2)NH,(CH_(3))_(3)N,C_(6)H_(5)CH_(2)NH_(2^.)

The correct increasing order of basic strength in, CH_(3)CH_(2)CN, CH_(3)CH_(2)NH_(2), CH_(3)N=CHCH_(3) is
