`CH-=C-CH=CH-CH_(3)` में प्रत्येक कार्बन परमाणु का संकरण बताइए ।

CH_(3)-CH=C=CH-CH_(3)

CH_(2)=CH-C-=C-CH=CH-CH_(3)

How many sigma and Pi bonds are present in each of the following molecules? (a) CH_(3) - CH= CH_(2) (b) CH_(3) - C -= C-CH_(3) (c ) HC -= C-CH = CH-CH_(3) (d) CH_(2) = C = CH CH_(3)

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
