1
Q
CH3F,CH2CI2 IS NONIDEAL
A
Because of redistribution of s/p character
2
Q
Dragos molecule have bond angle and bond energy always less than hybridization molecule
A
Only hybrid of group 15 having negative delta H of formation
PH3,NH3,AsH3,SbH3
Ans NH3
3
Q
Non hybrid orbital
s,p,d,f lp do not change the bond angle of orbital
In hybrid orbital
Sp3,sp2 the bond angle changes due to lp
A
INH3 IS MORE BASIC THAN PH3 BECAUSE IP PRESENT IN SP3 ORBITAL WHICH IS AWAY FROM NICLEUS
4
Q
Order of donation
A
NH3>PH3<ASH3<SbH3BiH3
Due to increase in size
5
Q
Shape of NH3 ,PH3
A
Pyramidal both
Ph3/Nh3 + h+ = ideal tetrahedral
Ph3/Nh3+ BH3= nonideal hybridization
