Assertion : Acetylene is formed when ethylene chloride or ethylidene chloride is heated with sodamide, \(\mathrm{NaNH}_{2}\). Reason : Both geminal dihalides and vicinal dihalides on dehydrohalogenation form alkynes.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Both assertion and reason are true and the reason is the correct explanation of the assertion.

Which of the following organic compounds has the same hybridisation as its combustion product, \(\mathrm{CO}_{2}\) ?
1 Ethane
2 Ethyne
3 Ethene
4 Ethanol
Explanation:
The combustion reaction of ethylene is \(\mathrm{C}_{2} \mathrm{H}_{2}+\dfrac{5}{2} \mathrm{O}_{2} \rightarrow 2 \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}\) Both \(\mathrm{C}_{2} \mathrm{H}_{2}\) or \(\mathrm{HC} \equiv \mathrm{CH}\) and \(\mathrm{CO}_{2}\) have "sp" hybridisation
