Dab tsi yog hydrides piav nrog piv txwv?

Hydride, ib chav kawm ntawm cov tshuaj sib txuas uas hydrogen tau ua ke nrog lwm lub ntsiab. … Txhuas thiab, tejzaum nws, tooj liab thiab beryllium hydrides yog nonconductors uas muaj nyob rau hauv cov khoom, kua, los yog gaseous daim ntawv. Txhua yam yog thermally tsis ruaj khov, thiab qee qhov tawg ntawm kev sib cuag nrog huab cua lossis noo noo.

Dab tsi yog hydrides thiab lawv faib li cas?

Hydrides tau muab faib ua peb pawg loj, nyob ntawm seb cov ntsiab lus ntawm hydrogen bonds rau. Peb pawg loj yog covalent, ionic, thiab metallic hydrides . Raws li txoj cai, hydride hu ua qhov tsis zoo ion ntawm hydrogen, H^{-, tseem hu ua hydride ion.}

Dab tsi yog hydrides hauv organic chemistry?

Hydride: (1) Ib tus hydrogen atom nrog tus nqi tsis zoo , H:^{- (lub hydride ion), lossis Qhov sib xyaw uas muaj cov ion no. … (2) Ib qho molecule uas muaj ib lossis ntau qhov sib txuas ntawm hydrogen thiab cov ntsiab lus tsawg dua electronegative dua hydrogen (piv txwv li, ib lub molecule uas xa hydride mus rau lwm lub molecule).}

Dab tsi yog hydrides piav qhia covalent hydrides?

Covalent hydrides yog kua lossis roj uas muaj cov ntsiab lus melting tsawg thiab kub , tshwj tsis yog hauv covrooj plaub (xws li dej) qhov twg lawv cov khoom raug hloov kho los ntawm hydrogen bonding. … Piv txwv li, txawm hais tias tsis hloov pauv, NH₃, H_{2O, thiab HF tau tuav ua ke hauv cov kua hauv lub xeev feem ntau los ntawm hydrogen bonding.}
