Question

Indicate the type of hybridization of each carbon atom in the following molecules:
(i) `CH_(3)-C-=CH-CH_(3)` (ii) `H_(2)C=C=CH_(2)`
(iii) `CH_(3)-CH=CH-CH_(3)` (iv) `CH_(3)-CH_(2)-CH_(3)`

Answer 1

(i) `overset(1)(C)H_(3)-overset(2)(C)-=overset(3)(C)-overset(4)(C)H_(3)`
Carbon -1 is linked with four atoms `= sp^(3)`-hybridization
Carbon-2 is linked with two atoms =sp-hybridization
Carbon-3 is linked with two atoms = sp-hybridization
Carbon-4 is linked with four atoms = `sp^(3)`-hybridization.
(i) `H_(2)overset(1)(C)=overset(2)(C)=overset(3)(C)H_(2) C_(1)=sp^(2), C_(2)=sp` and `C_(3)=sp^(2)`
(ii) `overset(1)(C)H_(3)-overset(2)(CH)=overset(3)(C)H-overset(4)(C)H_(3) C_(1)=sp^(3), C_(2)=sp^(2), C_(3)=sp^(2)` and `C_(4) = sp^(3)`
(iv) `overset(1)(C)H_(3) -overset(2)(C)H_(2)-overset(3)(C)H_(3)C_(1)=sp^(3),C_(2)=sp^(3), C_(3)=sp^(3)`
