Question

12.
In acetylene molecule, the two carbon atoms are
linked by
(a) One sigma bond and two pi bonds
(b) Two sigma bonds and one pi bond
(c) Three sigma bonds
(d)Three pi bonds​

Answer 1

Answer:

(A) is correct option

Explanation:

Acetylene has 1 sigma and two π-bonds

Answer 2

Answer:

option A is the correct answer.

Explanation:

Ethyne has a triple bond between the two carbon atoms.

In the diagram, each line represents one pair of shared electrons.

H−C≡C−H

Two carbon atoms have one sigma bonds and two pi bonds.

Hence the correct option is A.
