Solution
The correct option is B. 3
The structural isomer of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them.
In this given molecular formula i.e.C4H8 there are 5 structural isomers can be formed as follows:
1) but−1−ene
2) but−2−ene
3) 2−methylprop−1−ene
4) cyclobutane
5) 1−methylcyclopropane
But out of 5 structural isomers, only three belong to the alkene family i.e. but−1−ene,but−2−ene,2−methylprop−1−ene. and rest two belong to cycloalkane (i.e. cyclobutaneand1−methylcyclopropane)
Hence the correct answer is option B. 3
