How many primary amines are possible for the formula `C_4 H_(11) N`

Options

A. 1
B. 2
C. 3
D. 4

Answer

D

Explanation

`C_(4) H_(11) N to ` Primary amine `to C_(4) H_(9) NH_(2)`
`(1) CH_(3) CH_(2) CH_(2) - CH_(2) - NH_(2)`
` (2) CH_(3) -CH_(2) - underset( NH_(2) ) underset(|) (C H) - CH_(3)`
`(3 ) CH_(3) - overset( CH_(3)) overset(|) underset( CH_(3)) underset(|) (C ) - NH_(2)`
`(4 ) C_(2) H_(5) - underset( CH_(3) ) underset(|) ( CH) - NH_(2)`
