Chemistry · Tetravalency of carbon, shapes of simple molecules - hybridization (s and p)
Assertion Carbon shows tetravalency in all hydrocarbons. Reason Carbon shares it
Assertion Carbon shows tetravalency in all hydrocarbons. Reason Carbon shares its four valence electrons with other atoms and forms four single covalent bonds to get nearest noble gas formation.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
- C. Assertion is correct but Reason is incorrect.
- D. Both Assertion and Reason are incorrect.
Step-by-step solution
The assertion is correct because in all hydrocarbons, carbon forms four bonds (tetravalency), whether they are single, double, or triple bonds. The reason is incorrect because carbon does not always form four single bonds; it often forms double or triple bonds to achieve an octet. Therefore, the assertion is true, but the reason is false.
