1.	In the organic compound CH_(2)= CH - CH_(2) - CH_(2) - C -= CH,the pair of hybridised orbitals involved in the formation of C_(2)-C_(3) bond is (a) sp - sp^(2) (b) sp - sp^(3) (c) sp^(2) - sp^(3) (d) sp^(3) - sp^(3)
Answer» Solution :When both DOUBLE BONDS are PRESENT at equivalent positions, double bond is given preference while numbering the carbon chain. Thus, `underset(sp^(2))OVERSET(1)(C)H_(2) =underset(sp^(2))overset(2)(C)H - underset(sp^(3))overset(3)(C)H_(2)-underset(sp^(3))overset(4)(C)H_(2) - underset(sp)overset(5)(C) -= underset(sp)overset(6)(C)H` `:. C_(2) - C_(3)` bond is formed by overlap of `sp^(2) - sp^(3)` orbitals. Thus, option (c) is correct.
