Question

. A compound having a bond angle 180° is:
alkyne
alkane
alkene
cycloalkane

Answer 1

Explanation:

alkyne kk write the answer

Answer 2

Alkyne

Explanation:

• Alkynes also referred as acetylenes have linear geometry with carbon-carbon triple bond.
• The bond angle between triple bond and  also the bonded atoms is exactly 180° in acyclic compounds and so triple bond makes line as all four atoms lies linear.
• Linear geometry of alkynes is because of  directional character of the sp hybrid atomic orbitals of the Carbons in carbon-carbon triple bond.
• Ethylene and acetylene are samples of the alkynes. Carbon-carbon triple bond in acetylene is shortest (120 pm) and also the strongest (965 kJ/mol) of the carbon-carbon bond types.
