(a) How do bond length and bond strength vary in the following cases?
`C-C, C=C, C-=C`
(b) Arrange the `sp-,sp^(2-)` and `sp^(3)`-hybridization in increasing order of:
(i) bond length (ii) bond angle (iii) bond energy
(iv) size of orbitals (v)s-character

Answer

(a) Bond length order `C -C gt C=C gt C-=C` (b) (i) `sp-s lt sp^(2)-s lt sp^(3) -s (ii) sp^(3) lt sp^(2) lt sp`
(iii) `sp^(3) lt sp^(2) lt sp (iv) sp lt sp^(2) lt sp^(3)`
(v) `sp^(3) lt sp^(2) lt sp`
