The number of structural isomers for the compound with molecular formula C4H6{C_4}{H_6 } is:
A. 3
B. 7
C. 5
D. 9

Explanation

Solution

To solve this question, first we will name the isomers for the compound C4H6{C_4}{H_6}. And, then we will describe the few isomers one-by-one. We will also mention the isomers which is not structural.

Complete Step By Step Answer:
There are a total 9 structural isomers for the compound with molecular formula C4H6{C_4}{H_6}.
Some of them are 1 - butyne, 2 - butyne, 1,2 - butadiene, 1,3 - butadiene and cyclobutene.
Other isomers with this formula include methylenecyclopropane, 1 - methylcyclopropene, 3 - methylcyclopropene and bicyclo[1.1.0] butane.

  • 1 - butyne: 1 - Butyne puts the triple bond on the terminal carbon, permitting hydrogen to be accessible. Normally on the off chance that we essentially allude to Butyne we are alluding to since when there is definitely not a number recognizing where the alkyne is, we expect it is on the main carbon. It is also known as But - 1 - yne and Ethyl acetylene .
  • 2 - butyne: 2 - butyne is an alkyne with chemical formula CH3C≡CCH3C{H_3}C \equiv CC{H_3}. Produced artificially, it is a colorless, volatile, pungent liquid at standard temperature and pressure.
  • 1,2 - butadiene: 1,2 - Butadiene is a minor side-effect in the creation of 1,3 - butadiene . Thus, the creation and utilization of 1,3 - butadiene in the production of polymers, for example, manufactured elastic plastics and pitches may bring about the arrival of 1,2 - butadiene to the climate through different waste streams.
  • Cyclobutene: Cyclobutene is a cycloalkene. It is of interest as a fundamental value, not for practical applications. It is a colorless easily condensed gas. A modern synthesis involves the 2-step dehydration of cyclobutanol.
    Hence, the correct option is (D) 9.

Note:
In science, a structural isomer (or sacred isomer in the IUPAC terminology) of a compound is another compound whose particle has a similar number of molecules of every component, except with legitimately particular connections between them.
