Question

Which of the following organic compounds has same hybridisation as its combustion product (CO2\text{CO}_2)?

A

Ethane

B

Ethyne

C

Ethene

D

Ethanol

Step-by-Step Solution

The combustion product of the given organic compounds is carbon dioxide (CO2\text{CO}_2). In CO2\text{CO}_2, the central carbon atom is bonded to two oxygen atoms via double bonds (O=C=O\text{O=C=O}), so it has spsp hybridisation.

Let's evaluate the hybridisation of the carbon atoms in the given options:

  1. Ethane (CH3-CH3\text{CH}_3\text{-CH}_3): The carbon atoms form only single bonds and are sp3sp^3 hybridised .
  2. Ethyne (HC≡CH\text{HC}\equiv\text{CH}): Each carbon atom forms a triple bond and is spsp hybridised .
  3. Ethene (CH2=CH2\text{CH}_2\text{=CH}_2): The carbon atoms form a double bond and are sp2sp^2 hybridised .
  4. Ethanol (CH3CH2OH\text{CH}_3\text{CH}_2\text{OH}): The carbon atoms form only single bonds and are sp3sp^3 hybridised.

Therefore, ethyne has the same spsp hybridisation as CO2\text{CO}_2.
