Pi bonds in rings which are 7 member ed or less don't show GI as there is no possibilty for trans form in them

RE: Ionic equilibrium
@urvashi a and d both have ph=2
In a multiplying by 2(n factor) will give the normality hence log (10^2) will be the ph.As we calculate equivalents so for all the cases I took volume to be 1 l .so no. Of equivalents =10^2 (normality ×volume)
In d using direct formula
In b the salt is neutral salt as it is formed by strong acid h2so4 and strong Base nah
In c the poh value will be 2 
RE: Shm
@anikasharma
For Shm
F is directly proportional to x and is opposite to displacement
So here , it is given motion is shm
So F=Tx ( assume T is the constant)
Given F=kx^1/2
Equate the 2 and u get k=Tx^1/2 that increases with x

@anag
Yes they are same because GI is about the relative spatial arrangement of the groups . Say two groups 1 and 2..if 1 is above the plane and 2 below it is the same as 2 being above the plane and 1 below as the relative positioning is opposite to each other that is trans...same goes for cis
