Question

Which of the following statements is correct for ethyne molecule?

(a) Ethyne molecule consist of two C - C σ - bonds

(b) It has one π - bond

(c) It is a non - linear molecule

(d) Electron cloud between two C - atoms is cylindrically symmetrical

Answer 1

Answer is : (d) Electron cloud between two C - atoms is cylindrically symmetrical

Ethyne molecule is a linear molecule which consists of one C - C σ - bonds, two C - H σ - bonds and two C - C π - bonds. Electron cloud between two C - atoms is cylindrically symmetrical about the internuclear axis.
