(a) O2 and HCl
(b) O2 and N2
(c) O2 and C2H4
(d) O2 and C2H2​

Answer 1

Answer:

(c) O2 and C2H4 ɪꜱ yᴏᴜʀ ᴄᴏʀʀᴇᴄᴛ ᴀɴꜱᴡᴇʀ

Answer 2

Answer:

Because $O_{2}$ and $C_{2} H_{4}$ contain two covalent bonds, C is the correct answer.

Explanation:

One or even more pairs of electrons are shared between two atoms in a covalent bond.

Covalent Bonds Come in a Variety of Forms

1. Single Covalent Bond.
2. Double Covalent Bond.
3. Triple Covalent Bond.

$O_{2}$ - Covalent Bond of two atoms

$HCl$ - Single Covalent Bond.

$N_{2}$ - triple covalent bond'

$C_{2} H_{4}$- is made up of two carbon atoms joined by a double covalent bond.

$C_{2} H_{2}$ has a triple bond between its two carbon atoms.
