Vedclass · Answer

(B) The correct matching is as follows:$(A)$ Electron precise hydrides have the exact number of electrons needed to form covalent bonds. These are formed by group $14$ elements such as $CH_4$ and $SiH_4$. Thus,$A-(i)$.$(B)$ Saline hydrides (also known as ionic hydrides) are compounds formed between hydrogen and the most active metals,especially alkali and alkaline-earth metals such as $MgH_2$. Thus,$B-(iii)$.$(C)$ Electron-deficient hydrides are compounds in which the central atom has an incomplete octet,such as boron in $B_2H_6$. Thus,$C-(iv)$.$(D)$ Electron-rich hydrides have one or more lone pairs of electrons around the central more electronegative element,such as $H_2O$. Thus,$D-(ii)$.Therefore,the correct match is $A-(i), B-(iii), C-(iv), D-(ii)$.

List-$I$ (Type of hydride)	List-$II$ (Example)
$(A)$ Electron precise	$(i)$ $SiH_4$
$(B)$ Saline	$(ii)$ $H_2O$
$(C)$ Electron deficient	$(iii)$ $MgH_2$
$(D)$ Electron rich	$(iv)$ $B_2H_6$

List-$I$ (Fuels)	List-$II$ (Composition)
$A$. Water gas	$i$. $A$ mixture of $CO$ and $N_2$
$B$. Producer gas	$ii$. Methane
$C$. Coal gas	$iii$. $A$ mixture of $CO$ and $H_2$
$D$. Natural gas	$iv$. $A$ mixture of $CO$,$H_2$,$CH_4$ and $CO_2$

Match the following types of hydrides in List-$I$ with their examples in List-$II$.
