question_answer

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

A)  3                                            

B)  4

C)  5                                            

D)  6

Correct Answer: D

Solution :

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