Qhov kev txiav txim ntawm qhov pib yog muab raws li I > III > II > IV. Yog li, lo lus teb raug yog “Option D”.

Qhov kev txiav txim ntawm qhov pib yog dab tsi?

Qhov kev txiav txim ntawm qhov pib yog I>III>II>IV Ib khub ntawm electrons ntawm N yog yooj yim dua rau protonation hauv kuv thiab III ces hauv II. Mob muaj cov pa oxygen atom uas muaj -Kuv cuam tshuam vim nws yog qhov yooj yim dua li kuv.

Yuav ua li cas yog lub hauv paus ntawm muab compound?

Compound (C) yog ib qho zoo heev muaj zog nitrogeneous organic puagua ib khub ntawm ib qho nitrogen delocalize nyob rau hauv resonance thiab ua rau lwm nitrogen tsis zoo nqi thiab conjugate acid muaj ob qhov sib npaug resonating qauv. Yog li nws yog qhov yooj yim tshaj plaws nyob rau hauv muab compound.

Lub ntsiab lus twg muaj qhov tseem ceeb tshaj plaws?

Generically IUPAC txhais ib qho superbase ua "cov khoom sib xyaw uas muaj cov hauv paus loj heev, xws li lithium diisopropylamide." Superbases feem ntau txhais ua ob pawg dav, organic thiab organometallic.

Qhov twg yog qhov yooj yim tshaj plaws?

NI3 yog qhov yooj yim tshaj plaws vim tias Iodine muaj qhov tsis muaj d orbital li no nws tuaj yeem txais ib khub ntawm electrons los ntawm Nitrogen thiab pab hauv kev sib raug zoo. Tsis tas li ntawd, qhov tseem ceeb txo qis hauv pab pawg thiab hauv qhov no zoo li NI3 yog qhov yooj yim dua li lwm cov khoom sib txuas.
