The explanation for the correct answer
(c)
- is the simplest alkyne chemical compound with the chemical name Acetylene.
- The ethyne molecule features a triple bond between two carbon atoms, each of which is singly bonded to one other hydrogen atom. It can be noted that all four atoms align in a straight line with bond angles of approximately 180o.

The explanation for the incorrect answers
(a)
- The molecular geometry of is bent, with a bond angle of 120°.

(b)
- NO2 has an extra electron in an orbital on the nitrogen atom it will result in a higher degree of repulsions. However, if we take the one lone electron or the single-electron region there is less repulsion on the two bonding oxygen atoms. So the repulsions are not identical. As a result, the oxygen atoms are spread widely.
- The bond angle is 134o which is actually far from the ideal angle of 120o. NO2 molecular geometry will be bent.

(d)
- The structure of SnCl2 is a trigonal pyramidal shape ( V shape) due to the presence of lone pair of electrons.

Hence, the correct option is (C) as and both are linear with a bond angle of 180° so is isostructural with .
