11Ans to second one is (i)
Solid PCl5 exists as [PCl6-] and [PCl4+]
[PCl6-] is sp3d2
[PCl4+] is sp3
You want me to draw their structures ??
11@ organic :
i think you got confused with PBr5 which in solid state exists as PBr4+ and Br-
1the two p-orbitals that overlap to form the pi bond must be parallel to each other for maximum overlap to occur.this forces the transition state formed by one carbon and two hydrogens must lie in the same plane as the transition state formed by other one carbon and two hydrogens .this means all six atoms lie in the same plane and electrons in p-orbital occupy a volume of space above and below this plane.
The nodal plane in the Î bond of ethene is located in Plane parallel to molecular plane.ans is b.
11Thanx all of u for the participation.....now 1 elementary qsn, what is the hybridisation of Carbon in graphite......U'll be shocked to know the ans given at the end of the book.
19The geometry of the hybridized orbital is trigonal planar. This is the reason why each carbon atom within graphite has three nearest neighbors within the graphite sheets. One of the p-orbitals is left unaffected. This last p-orbital overlap with those from neighboring carbon atoms, in a sideways manner, to form the distributed pi-bonds that reside above and below each graphite sheet.
11And now the ans at the end of the book for the hybridisation of C in graphite :-
sp2+Î 3
19what i can say over here is that there must have been some other question given along with this one,whose answer turns out to be (∩/3)!!!
11Why don't u check for urself to clear this confusion.....
