sp Hybridisation

Q.

Define hybridization.

Q.

The most acidic hydrogen atoms are present in:

1. Ethane

2. Ethene

3. Ethyne

4. Benzene

Q. Assertion: The carbon in ethyne is more eletronegative compared to ethene
Reason: More is the s-character more electronegative is the atom

1. Both assertion and reason are correct but reason is not the correct explanation of the assertion
2. Both assertion and reason are correct and reason is also the correct explanation of the assertion
3. Assertion is correct but the reason is wrong
4. Assertion is wrong but the reason is correct
