Two carbon atoms (Group 14) bond with two hydrogen atoms (Group 1) to form acetylene (C2H2). How would each carbon atom in acetylene bond?(1 point)

Each carbon atom would share one pair of electrons with the other carbon atom and three pairs with each hydrogen atom.

Each carbon atom would share one pair of electrons with the other carbon atom and two pairs with each hydrogen atom.

Each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom.

Each carbon atom would share one pair of electrons with hydrogen and one pair with the other carbon atom.

Respuesta :

In acetylene each carbon atom share one pair of electrons with hydrogen atom and three pairs with the other carbon atom.

Carbon atom has four electrons its outermost shell it means that it needs four electrons to become stable. In acetylene, two carbon atoms covalently bonded three pairs of electron with each other and the one remaining pair is covalently bonded with two hydrogen atoms.

In this way the carbon as well as hydrogen atoms get stability so we can conclude that in acetylene each carbon atom share one pair of electrons with hydrogen atom and three pairs with the other carbon atom.

In C2H2, each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom.

Acetylene has the molecular formula C2H2. We must recall that carbon is a member of group 14 and it is always tetravalent in all its compounds. Hydrogen is always univalent in its compounds except in hydrides.

Since carbon is always tetravalent and hydrogen is univalent,each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom in C2H2.
