The formulas for ethane, ethene, and ethyne are C 2 H 6 C2H6 , C 2 H 4 C2H4 , and C 2 H 2 C2H2 , respectively. Rank these compounds by the length of the carbon–carbon bond.

Respuesta :

Answer:

Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)

Explanation:

The types of bonds present are:

a) Ethane : single bond

b) Ethene : double bond (one sigma one pi)

c) Ethyne: triple bond (one sigma and two pi bonds)

More the number of bonds lesser the bond length.

Thus the order of bond length of carbon-carbon bond will be:

Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)
