Which of the following orders is correct? (1) SbH_(3)gt NH_(3) gt AsH_(3) gt PH_(3)-" Boiling Point" (2) NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3)-" Thermal Stability" (3) NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3) - "Basic Character" (4) NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3)- "Bond Angle"

The decreasing order of melting points is NH_(3) gt (CH_(3))_(3) N gtPH_(3) .

The bond angle follows the order: NH_(4)^(+) gt NH_(3) gt NH_(2)^(-)

Order H_(3)PO_(4) gt H_(2)SO_(4) gt HNO_(3) gt HCl is correct for :-

NH_(3), PH_(3), AsH_(3),SbH_(3) ( increasing thermal stability)

Amost NH_(2) , PH_(3),AsH_(3) and SbH_(3) the one with highest bolding point is
