Question
Figure shown is a graph, at a certain time t, of the displacement function S(x,t) of three sound waves 1,2 and 3 as marked on the curves that travel along x–axis through air. If P1 ,P2 and P3 represent their pressure amplitudes respectively, then correct relation between them is :
- P1 > P2 > P3
- P3 > P2 > P1
- P1 = P2 = P3
- P2 > P3 > P1
The correct answer is: P3 > P2 > P1

The rate of 
reaction depends on the effectiveness of the nucleophile in ejecting the leaving group. Nucleophilicity is the affinity for C atom, while basicity is the affinity for proton
In both cases, a new bond is formed. If a new bond is formed between the anion and proton, the species acts as a base. If a new bond is formed between the anion and C atom, the species acts as nucleophile
