Question

Which of the following is an isomer of $ C{H_3}C{H_2}C{H_2}C{H_2}OH $ ?
A. $ C{H_3}C{H_2}C{H_2}OH $
B. $ C{H_3}CH(OH)C{H_3} $
C. $ C{H_3}C{H_2}C{H_2}C{H_3} $
D. None of the above

Answer 1

Hint :Isomers are molecules with similar molecular formulas — that is, the same number of atoms of an element — but different atomic configurations in space, according to chemistry. Isomerism refers to the presence or potential of isomers. Isomers don't always have the same chemical or physical properties as one another. Structural or constitutional isomerism, in which the bonds between the atoms vary, and stereoisomerism or spatial isomerism, in which the bonds are the same but the relative positions of the atoms differ, are the two major types of isomerism.

Complete Step By Step Answer:
A hydroxyl group is a functional group that binds to molecules that contain bound oxygen and hydrogen atoms. Both alcohols and carboxylic acids benefit from this functional group, which is also spelled hydroxy. Alcohols are carbon molecule chains with a functional hydroxyl group on one side. Alcohols have a small polarity due to the electronegativity of the oxygen, which allows them to interact with other polar molecules including water and other solutes.
So, now according to the given question, None of the given compounds is an isomer of $ C{H_3}C{H_2}C{H_2}C{H_2}OH $ .
 1-butanol $ C{H_3} - C{H_2} - C{H_2} - CH2 - OH\; $ has 4 C atoms whereas $ C{H_3}C{H_2}C{H_2} - OH\;and\;C{H_3}CH\left( {OH} \right)C{H_3} $ have 3C atoms only. Isomers have the same molecular formula, i.e, they should have the same number of C atoms. Similarly, $ C{H_3}C{H_2}C{H_2}C{H_3} $ ​ contains no O atom whereas $ C{H_3}C{H_2}C{H_2}C{H_2} - OH\; $ has one O atom.
Hence the correct option is :( D)None of the above.
