Question

19. Which of the following does not contain a multiple bond"?
(a) CH3CN (b) HS
(c) CO2
(d) HBO
​

Answer 1

Answer:

Option A

CH3CN is the answer

Answer 2

Answer:

HS does not contain a multiple bond.

Explanation:

• $CH_{3} CN$ (Acetonitrile), is contain a triple bond with a Nitrogen atom. Hence it contains a multiple bond.
• HS contain a single sulfur atom that makes a bond with two hydrogen atom. Hence it does not contain a multiple bond.
• $CO_{2}$ , here carbon shares its two valence electrons with two oxygen atoms. Hence, it contains a double bond.
• HBO, here Boron and Oxygen form a triple bond because Boron has a high electronegative value and has the power to draw electrons from the B-OH bond.
