How many primary amines including stereoisomers are possible for the molecular formula `C_(4)H_(11)N` .

Options

A. Five
B. four
C. three
D. two

Answer

A

Explanation

primary amine has the general formula `R-NH_(2)` Thus different possibilities can be worked out by changing the nature of alky1 group
`CH_(3)CH_(2)CH_(2)CH_(2)NH_(2)`
`underset("Optically active"(+,-))(CH_(3)CH_(2)overset(NH_(2))overset(|)CHCH_(3)) CH_(3)overset(CH_(3))overset(|)CHCH_(2)NH_(2) CH_(3)underset(CH_(3)) underset(|)overset(CH_(3))overset(|)CNH_(2)`
Thus a total of five `1^(@)` amines are possible of which two are optically active .
