Question

Choose the pair of chain isomer:

• A. CH₃CHBr₂ and CH₂BrCH₂Br
• B. 1-propanol and 2-propanol
• C. Neo-pentane and iso-pentane
• D. Diethyl ether and methly-n-propyl ether

Answer 1

The correct option is C

Neo-pentane and iso-pentane

Now, first of all, what is neo-pentane?

Yeah, do you remember, we discussed the same in the videos.

As we can see, there is only difference in the arrangement of carbon atoms.

[Note :- In chain isomers, there is only difference in the arrangement of carbon atoms .]

$C{H}_{3}CHB{r}_2$ and $C{H}_{2}BrC{H}_{2}Br$ ( Position of Br is different not carbon, and molecular formula is also different.)

Same is the case in the other two options.
