hope, Iam not mistaken

Each entry of Column 1 can be matched with one or more than 1 entries of Col. 2.
Column 1 Column 2
A) B2H6 P) Can act as lewis acid
B) BF3 Q) Intramolecular lewis acid-base interaction
C) ICl3 R) Nonpolar
D) SiF4 S) Nonplanar
T) Can dimerise
Maine bhi aisehi hope mein dhoka khaaya tha....[3]
Anyways, the answers are -
A) -P,R,S
B) -P,Q,R
C) -P,T
D) -P,Q,R,S
A)B2H6 acts as lewis acid B2H6 + 2H− → 2BH4−
Due to tetrahedral shape it is non polar and non planar
B)BF3 acts as Lewis acid
Its triangular planar structure gives dipole moment =0
C)ICl3 acts as lewis acid in reaction ICl3+Cl-→ICl4-
It exists as dimer (I2Cl6 )
D)SiF4 is used as lewis acid(in complex organic reactions )
It has tetrahedral structure and has dipole moment =0
Thnx nikunj, but still doubts persist...
A) R, S okay ; but why/how P...?
B) P,R okay ; but Q...??
Wht does "Q" actually mean btw ?
C) Isn't ICl3 nonplanar n hence nonpolar ? Aur yeh reaction ke alaawa koi aur tareeka batao yaar, je sab apne ko yaad nahi rehta.
D) Same here,,, Lewis acid, lekin kaise ?? n wht is this intramolecular acid-base interaction ?
