Which will be the least stable resonation structure:
(A) `CH_(2)=CH-CH^(+)-CH^(-)-NH_(2)`
(B) `CH_(2)-CH^(+)-CH=CH-NH_(2)`
(C) `CH_(3)-CH=CH-CH_(2)-NH_(2)^+`

CH_(3)CH_(2)CONH_(2)overset(X)to CH_(3)CH_(2)CH_(2)NH_(2) X is:

The least and most stable resonating structure respectively are: (1) CH_(2)=CH-CH-CH-C-CH_(3) (2) CH_(2)=CH-CH-CH=C-CH_(3)O^(Theta) (3) CH_(2)-CH-CH=CH-C-CH_(3) (4) CH_(2)=CH-CH=CH-C-CH_(3) (А) 1,4 (В) 2,3 (С) 4,1

Select the alkyl halide and nucleophile that will give each of the following products. (a) CH_(3)-CH_(2)-CH_(2)-NH_(2) (b) CH_(3)-CH_(2)-O-CH_(2)-CH_(3) (c) CH-=C-CH_(2)-CH_(2)-CH_(2) (d) (CH_(3))_(2)CHS(CH_(3))_(2) (e) C_(6)H_(5)-O-CH_(2)-CH_(3)

Arrange the basic strength of the following compounds. (i) CH_(2) = CHCH_(2)NH_(2) (ii) CH_(3)CH_(2)CH_(2)NH_(2) (iii) CH -= C - CH_(2)NH_(2)
