Which multiple bond present in CO_(2), C_(2)H_(4), N_(2) and C_(2) H_(

1.	Which multiple bond present in CO_(2), C_(2)H_(4), N_(2) and C_(2) H_(2) ? Draw Lewis and simple bond structure of these molecules.
Answer» Solution :(a) Carbon dioxide (CO2) : In CO2 molecule two double bond present. Electron pair (four electron ) between C and O ATOM. Between C & O two `e^(-)` pair (b) Ethene `(C_(2)H_(4))` : In its one double bond (C = C) between two carbon and four single C - H bond. In this between two carbonatoms two electron pairs means four electrons are there so double bond is form. (c) Dlnitrogen: `(N_(2)) ` (d) Ethyne `(C_(2)H_(2))` :In this one triple bond between two carbon and two C -H single bond. ln this between two carbon three carbon pairs (slx electrons) from three covalent lent bond. LEWIS and simple REPRESENTATION of bonds in Ethyne
