Total number of acyclic and cyclic isomers possible for molecular formula `C_(4)H_(6)` is

Options

A. 5
B. 7
C. 9
D. 8

Answer

C

Explanation

Total number of acyclic and cyclic isomers possible for molecular formula `C_4H_6` is 9 which are as follows:
(i) ` CH_3 - CH_2 - underset("1-butyne")(C -=CH)`
(ii) `CH_3 - C -= underset("2-butyne")(C-CH_3)`
(iii) `CH_2 = CH- underset("But-1,3-ene")(CH = CH_2)`
(iv) ` CH_3 - CH = underset("But-2,3-ene")(C = CH_2)`
