Question

What is the number of electrons shared in the multiple carbon-carbon bond in one molecule of 1-pentyne?

(1) 6
(2) 2
(3) 3
(4) 8

Answer 1

Answer: The correct answer is Option 1.

Step-by-step explanation:

1-pentyne is a hydrocarbon which has a triple bond present between carbon and carbon atoms. This is considered as an unsaturated hydrocarbon and an alkyne.

To form a single bond, number of electrons required are 2.

Here, triple bond is present between carbon and carbon atoms, so number of electrons required to form this bond will be
`(2* 3)=6`

Hence, the correct answer is Option 1.

Answer 2

The correct answer for the given question above would be option A. The number of electrons shared in the multiple carbon-carbon bond in one molecule of 1-pentyne is 6. -YNE is considered as a triple bond. This would mean 3 pairs of electrons of 6 electrons. Hope this answers your question. Have a great day!
