निम्नलिखित अणुओं में सिग्मा और पाई बन्धों की कुल संख्या निकालिए:
(a) `C_(2)H_(5)Cl`
(b) `CH_(2)Cl_(2)`
(c) `CH_(3)-CH=CH-C-=C-H`

Explanation

`underset("पाई बन्ध =0")(underset("सिम्मा बन्ध = 7")(H- underset(H)underset(|)overset(H)overset(|)C-underset(H)underset(|)overset(H)overset(|)C-Cl))" " underset("पाई बन्ध =0")(underset("मिग्मा बन्ध = 4")(H-underset(H)underset(|)overset(Cl)overset(|)C-Cl))" "underset("पाई बन्ध =3")(underset("सिग्मा बन्ध = 10")(H-underset(H)underset(|)overset(H)overset(|)C-overset(H)overset(|)C= overset(H)overset(|)C-=C-H))`
