33.

નીચેના પૈકી કયું સંયોજન મહત્તમ આયનીય લક્ષણ ધરાવે છે ?

SnCl₂
MgCl₂
LiCl
BeCl₂

34. નીચેનાં સંયોજનમાં સહસંયોજક લક્ષણોનો યોગ્ય ક્રમ દર્શાવો :

$BCl subscript 3 space greater than space BeCl squared space equals space LiCl$
$BCl subscript 3 space greater than space BeCl subscript 2 space equals space LiCl$
$BCl subscript 3 space greater than space LiClk space greater than space BeCl subscript 2$
$LiCl space greater than space BeCl subscript 2 space greater than space BCl subscript 3$

35. નીચેનાની ધ્રુવીય દ્વાવકમાં દ્વાવ્યતાનો યોગ્ય ક્રમ જણાવો :

RbI < CdI₂ < pbO₂
CdI₂ < RbI < PbO₂
PbO₂ < CdI₂ < RbI
PbO₂ < RbI < CdI₂

36. નીચેનાં સંયોજનોમાં ગલનબિંદુનો યોગ્ય ક્રમ દર્શાવો :

$Cs subscript 2 CO subscript 3 space less than space Li subscript 2 CO subscript 3 space less than space Rb subscript 2 CO subscript 3 space less than space straight K subscript 2 CO subscript 3$
$space Li subscript 2 CO subscript 3 space less than straight K subscript 2 CO subscript 3 space less than space Rb subscript 2 CO subscript 3 space less than space Cs subscript 2 CO subscript 3$
$space Li subscript 2 CO subscript 3 space less than straight K subscript 2 CO subscript 3 less than space Cs subscript 2 CO subscript 3 space less than space Rb subscript 2 CO subscript 3 space$
$straight K subscript 2 CO subscript 3 less than space Cs subscript 2 CO subscript 3 space less than space Rb subscript 2 CO subscript 3 space less than space space Li subscript 2 CO subscript 3$

space Li subscript 2 CO subscript 3 space less than straight K subscript 2 CO subscript 3 space less than space Rb subscript 2 CO subscript 3 space less than space Cs subscript 2 CO subscript 3

ફેજાનના નિયમ મુજબ જેમ ધન આયનનું કદ વધે, તેમ સહસંયોજક લક્ષણ ઘટે તેથી ગલનબિંદુ વધે.

$rightwards arrow with Li to the power of plus space less than space straight K to the power of plus space less than space Rb to the power of plus space less than space Cs to the power of plus on top space$ કદ વધે.

$therefore space rightwards arrow with Li subscript 2 CO subscript 3 space less than space straight K subscript 2 CO subscript 3 space less than space Rb subscript 2 CO subscript 3 space less than space Cs subscript 2 CO subscript 3 on top$ ગલનબિંદુ વધે.
