Solution

The correct options are
A Hinsberg`s method
B Fractional distillation method
C Hoffmann`s method
Hinsberg's test is a chemical reaction that is used to distinguish primary, secondary and tertiary amines.

$1^{0} a m i n e$

$2^{0} a m i n e$

$3^{0} a m i n e$
It does not react with benzene sulfonyl chloride.

Seperation by fractional distillation method is also possible if $3^{0}$ amine is first removed in a constant boiling mixture with ammonia.

$H o f f m a n n ‘ s m e t h o d : -$
$1^{0} a m i n e + d i e t h y l o x a l a t e ⟶ s o l i d o x a m i d e$
$2^{0} a m i n e + d i e t h y l o x a l a t e ⟶ l i q u i d o x a m i c e s t e r$
$3^{0} a m i n e + d i e t h y l o x a l a t e ⟶ n o r e a c t i o n$

$v i c t o r m e y e r t e s t : -$
This test used to distinguish $1^{0}, 2^{0} a n d 3^{0}$ alcohols.
