Question

whish molecule contains six bonding electrons? a)C2H4 b)C2F6 c)H2O d)NF3?

​

Answer 1

Answer:

C2H4

Explanation:

because it is a covalent bond, so they share electrons. making 6 electron pairs. there is 6 pair of electrons which is from 4 (C-H) and 2 from (C=C).

Answer 2

Answer:

The correct answer is a)C2H4

Explanation:

The structure of $C_{2} H_{4}$ has six bonding electrons. This molecule is called as Ethylene.

This is because, when bonding is done between two atoms, each atom shares a pair of electron with each other. Thus for every one bond, two electrons are shared between two atoms.

As in the case of Ethylene, the Carbon molecules has 4 bonding electrons where, each Hydrogen molecule shares one bonding electron with the Carbon atom. In total, there are two Carbon atoms, thus the total bonding electrons in Carbon is 2.

On the whole, two bonding electrons of Carbon and four bonding electrons of Hydrogen give six bonding electrons in $C_{2} H_{4}$. Hence. the correct option is option a) $C_{2} H_{4}$.
