What is the total number of sigma and pi...

What is the total number of sigma and pi bonds in the following molecules ? (a) `C_(2) H_(3) Cl (b) CH_(2) Cl_(2)`
` (c) H_(3) C - overset(H)overset(|)C = overset(H)overset(|)C - C - H`

Text Solution

Verified by Experts

(a) is `(c) H - overset(H)overset(|)C = overset(H)overset(|)C - Cl` (5 ` sigma ` bonds ,one `pi` bond )
(b) is `H- overset(H)overset(|)underset(Cl)underset(|)C - Cl` (only 4 ` sigma ` bonds )
(c) is `H- overset(H)overset(|)underset(H)underset(|)C -overset(H)overset(|)C -=overset(H)overset(|)C- C-=C - H` (10 `sigma` bonds , `3 p i` bonds)
