NEET Solved Paper 2014 Question 45

Question: Which of the following organic compounds has same hybridisation as its combustion product $ -(CO _2) $ ? [AIPMT 2014]

Options:

A) Ethane

B) Ethyne

C) Ethene

D) Ethanol

Show Answer

Answer:

Correct Answer: B

Solution:

Hybridisation of carbon = $ sp^{3} $ -number of $ s{p^{3-number,\pi -bonds}} $

In $ CO _2,(O\underset{1\pi }{\mathop{=}},C\underset{1\pi }{\mathop{=}},O) $

hybridisation of carbon = $ s{p^{3-2}}=sp $ In ethyne or acetylene,

$ C _2H _2,,(H-C\overset{2\pi }{\mathop{\equiv \equiv }}C-H) $ hybridisation of carbon = $ s{p^{3-2}}=sp $
