Which branched open chain isomer of the ...

Which branched open chain isomer of the hydrocarbon having molecular mass 72u produces only one mono subsitituted alkyl halide-

A

pentane

B

neopentane

C

isohexane

D

neohexane

Text Solution

Verified by Experts

The correct Answer is:
B
Among the given four compounds, pentane has no branched open chain structure.
In case of neohenxane, molecular mass exceeds 72u. All the H atoms present in neopentane are equivalent while all the H-atoms present in isohexane are not equivalent.
Therefore, neopentane can produce only one mono substituted alkyl halide.
