Indicate the sigma and pi bonds in the following molecules: (i) C_(6)H_(6) (ii) C_(6)H_(12) (iii) CH_(2)Cl_(2) (iv) CH_(2) = C = CH_(2) (v) CH_(3) NO_(2) (vi) HCONH CH_(3)

Indicate the sigma and pi bonds in the following molecules: (i) C_(6)

1.	Indicate the sigma and pi bonds in the following molecules: (i) C_(6)H_(6) (ii) C_(6)H_(12) (iii) CH_(2)Cl_(2) (iv) CH_(2) = C = CH_(2) (v) CH_(3) NO_(2) (vi) HCONH CH_(3)
Answer» Solution :(i) `C_(6)H_(6)`: In `C- C sigma` bond In `C - H sigma` bond In `3C = C pi` bond (ii) `C_(6)H_(12)`: In `12C- H sigma` bond In `6C- C sigma` bond zero `pi` bond (iii) `CH_(2) Cl_(2), H underset(sigma)(-) underset(underset(Cl)(\|sigma))overset(overset(H)(\|sigma))( C)overset(sigma)(-) Cl` In `2 C - H sigma` bond In `2C - Cl sigma` bond TOTAL `4 sigma` bond (iv) `CH_(2) = C = CH_(2)`: In `4C - H sigma` bond In `2C - C sigma` bond In `2C = C pi` bond (v) `CH_(3)NO_(2)`: In `3C - H sigma` bond In `2N - O sigma` bond In `1N = O pi` bond `HCONHCH_(3)`: In `4C - H sigma` bond and In `N - H sigma` bond `Hunderset(sigma)- overset(overset(O)(pi\|\|sigma))(C )underset(sigma)- overset(overset(H)(\|sigma))(N)underset(sigma)- underset(underset(H)(sigma\|))overset(overset(H)(\|sigma))(C ) underset(sigma)- H` In `2C- N sigma` bond In `1C - O sigma` bond In `1C = O sigma` bond In `1C = O pi` bond
