question_answer

Number of isomers possible for \[{{\text{C}}_{\text{4}}}{{\text{H}}_{\text{8}}}\text{O}\]is:

A)  3                                            

B)  4                            

C)  5                              

D)  6

Correct Answer: D

Solution :

There are 6 isomers possible for the compounds having molecular formula \[{{\text{C}}_{\text{4}}}{{\text{H}}_{\text{8}}}\text{O,}\] which are as follows : (i) \[C{{H}_{3}}C{{H}_{2}}\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-C{{H}_{3}},\]                               (ii) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}CHO,\] (iii) (Iv) (v) and        \[\underset{(vi)}{\mathop{C{{H}_{2}}=CH-C{{H}_{2}}C{{H}_{2}}OH}}\,\]
