How many carbon atoms are there in the simplest alkane capable of exhibiting chain isomerism?

Athree
Bfive
Cfour
Correct Answer
Dsix

Solution

$$CH_4$$ has no chain isomer. $$C_2H_6$$ has no chain isomer. $$C_3H_8$$ has no chain isomer. $$C_4H_{10}$$ has 2 chain isomers. Therefore, 4 carbon atoms. Option C is correct.
