Question

Q20. Which of the following molecules contains a coordinate bond? (A) SO2 (B) CO2 O C) CH4 (D) MgC2​

Answer 1

Answer:

yes

Explanation:

I have explained in the picture

Answer 2

Among the given molecules, $SO_{2}$ contains a coordinate bond.

Explanation: Coordinate bonds are formed when a pair of electrons is shared from a single atom. It is a type of an alternative covalent bond

Sulphur dioxide contains a coordinate bond as:

• The sulphur atom contains 4 unshared electrons which means it has two lone pairs to donate.
•  One lone pair is donated by the sulphur atom to the oxygen atom, which forms a coordinate bond between sulphur and a molecule of Sulphur dioxide.
• The octet of oxygen is also completed by accepting this lone pair.
• The coordinate bond of sulphur dioxide is shown in the attached file.
