Question

Reason
All carbon atoms in alkanes are $$sp-$$hybridized.
Assertion
Alkanes having more than three carbon atoms exhibit chain isomerism.

A
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
B
Assertion is correct but Reason is incorrect
C
Both Assertion and Reason are incorrect
D
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Solution
Verified by Toppr

Correct option is C. Assertion is correct but Reason is incorrect
Chain isomerism can be shown by alkane having more than $$3$$ carbon chain it can show n-isomer, iso-isomer, neo-isomer etc.
Alkane having $$sp^3$$ hybridized carbon, while alkene having $$sp^2$$ and alkyne having $$sp$$ hybridized carbon
so Assertion is true but reason is false.
Hence option C is correct answer
